HEPA filter

The problem is that, as consumers, we don’t really know enough about these products to make a good decision when it’s time to buy one. Go online, and you’ll see any number of products on offer, from ionisers that release charged particles to separate the dust from the air, to humidifiers and other similar products that claim they will improve the air quality by pushing the dust out of the air, and air filters that work like a water purifier, in that it sucks in the air from the room, pushes it through a filter, and pushes clean air out. These use High Efficiency Particulate Air (HEPA) filters (or HEPA-type filters in cheaper models), and are used in hospitals as well – most people recommend avoiding ozonisers and ionisers. “Technology such as Ozone generators, which produce significant amounts of ozone, a strong oxidant gas which can oxidise many other chemicals are to be avoided at all cost,” Singh adds. “Negative ionisation technology is also debated upon for its by-product being ozone.” This was also reiterated to us by Sharp.

We’d go a step further and suggest considering only using purifiers that have a HEPA filter, not a HEPA-type filter, since HEPA is a standard which is tested and certified, so it ensures that you’re getting something that actually works. “You want the purifier to filter out PM2.- that’s particles that are 2.microns in size,” explains Dr. Mahesh Gupta, Chairman and Managing Director, Kent RO systems. The company is well established in water purification in India, and it has been in the air purifier market for a couple of years now. “You want a purifier that has a proper HEPA filter, which you should change every six months to one year.”

Aside from the HEPA filter, many companies have other filters such as pre-filters, as Singh pointed out. Altanta Healthcare’s CEO Vibhor Jain adds that consumers should look at the stages of filtration to make sure that as many harmful types of particles are being removed. “An ideal Air Purifier should have between 5-filters that include a Pre-filter, ESP filter, Molecular Sieve Media, HEPA/ ULPA, Activated Carbon, Cold Catalyst, and Fibre Filter,” he says, adding that the grade, or quality, of the filters is also important. “When we speak of quality or grade of the filters, we must make note of the thickness of the filters, type of HEPA filter used, Carbon type, material and surface area of the filters. This is the core of any filtration technology and goes on to define the efficiency of filtration.”

A lack of standards

Looking for a genuine HEPA filter is one of the ways that you can get around the lack of standards for air purifiers in India. Today, you could slap a filter and a fan together and sell it as an air purifier – in the US and in China there are several stringent standards and testing that is done to ensure that air purifiers up to the standards, but this is missing in India.

Girish Bapat, Director, West and South Asia for the Swedish company Blueair, says that part of the problem is that the industry in India is very nascent. “There are no standards right now, and we have been lobbying to ensure that there is a proper standard in place in India, that all manufacturers have to meet,” he says. “Right now, you can have to look at the CADR (Clean Air Delivery Rate) and the Air Change Per Hour, which is how many times the purifier cleans the air per hour,” he adds, “in order to get a good idea of whether it meets your needs. But instead many manufacturers just say, ‘this clears 100 square feet and that clears 200’, which is not telling the consumer anything.”

Bapat also stresses on the importance of a HEPA filter, and adds, “A HEPA filter will remove most of the PM 2.5, allergens and mites, from the air. It an also filter out smaller particles, like cigarette smoke,” he adds. “You should check the particle size that is being filtered, it should be 0.to 0.which catches even viruses that make people fall sick. But that doesn’t remove bad odours and pollutants in gases. For that, activated carbon is best. Sulphur gases and carbon fumes from the outside, cooking releases gases, so a carbon filter is very important too.”

The problem is that many manufacturers don’t give details to the degree that Bapat is suggesting. You’ll find some mentioning the CADR, others talking about the effective area that the purifier can clear, and yet others talking about particle sizes; it’s rare to see all this information together in one place.

Xiaomi is another company that entered the air purification space recently – it launched its first purifier last year, and entered India with the second generation Xiaomi Mi Air Purifier this year. Jai Mani, India – Product Manager for Xiaomi – believes that there is need for an industry standard. “There are already some really good standards in place,” says Mani. “In China, in the US, in Europe. I don’t think we need to replicate this but instead, we should have an industry level agreement to ensure that purifiers being sold in India meet these international quality standards.” “We had wanted to do that in time for the Air Purifier launch but it didn’t work out,” he adds, “but we’re going to keep working with the industry to ensure that it’s in place by the time we launch our next product.”

Ionizer Air Purifiers

Ionizers function much like electrostatic air cleaners do, except they exclude the collection plate. Instead, these devices  emit oppositely charged ions into the air which bind with dust, allergens and other inherent fragments, causing them to fall to the ground, where they can be vacuumed up.

Mechanical Air Filters Mechanical air filters are the most important means of air purification. They trap toxic wastes in one or more neatly interlaced sieves. HEPA (High Efficiency Particulate Air) sieves absorb as much as 99.percent of all the matter and allergens passing through them and are sometimes coupled with carbon or activated charcoal pre-filters.  In most cases, these will be good enough for the  elimination of tobacco smoke. However, if you want to get really serious, ULPA (Ultra Low Penetration Air) filters are also available; these can trap even more minuscule particles like mold spores and bacteria.

Regardless of the filtering procedure selected, one should examine two metrics before buying an air filter: the Efficiency Rate and the Clean Air Delivery Rate (CADR). The Efficiency Rate measures roughly how frequently the device can fully exchange the air in a specific size of room’s.  Your device should be able to clean the room it will be used in at least six times per hour for maximum efficiency. A unit’s CADR, on the other hand, determines the amount of air the cleaner can efficiently filter (i.e., how quickly it does its job). The higher the CADR rating, the quicker it purifies the air. Your unit should be rated to at least two-thirds that of the room’s square footage. So, for example, if you plan to cleanse an x room (80 square feet), you’ll want a filter with a CADR rating of at least 53.

Ozone Generator Air Purifiers

Ozone Generators are one group of air cleaners you should refrain from using at all costs. They apparently function by producing and discharging ozone, a molecule comprised of three oxygen atoms, one of which divides and blinds to pollutants.

Manufacturers of these devices state clearly that it has the capacity to not only disinfect the air, but to also eliminate all foul odors in a room. This unique dual feature makes the device one of the best air purifier for smoke.

However, the EPA has found that when functioning as advertised, these purifiers do very little but consume electricity. According to the EPA website: “Available scientific evidence shows that at concentrations that do not exceed public health standards, ozone has little potential to remove indoor air contaminants.” In addition, the high concentrations of ozone required to perform effective purification are the same concentrations that are dangerous to humans.

Many types of air purifiers are available on the market today. After some research and market reviews, we identified the most popular and best air purifiers for smoke.

Honeywell 50250-S True HEPA Air Purifier 390 sq ft

Honeywell 50250-S is a suitable option if you are looking the best air purifier for smoke odor. It is a true HEPA round air purifier with 250 CADR. Due to its 1x 1x 1inches dimensions and 2pounds weight. With its pure HEPA filter, Honeywell 50250-S can remove 99.97% of common airborne pollutants having the smallest size of 0.microns.

This air purifier features speeds, and is capable of cycling the air 4.times per hour in an approx. It’s ideal for a space of 390 square feet. It promises that you have a selectable and practical range and also not too complex to operate.

Used from

Cigar and cigarette smoke contains a lot of harmful particles and gases. The annoying smoke odor can prove to be overwhelming.

The best air purifier for smoke is designed and manufactured to address the odor and airborne particles.

It is worth mentioning that every air purifier is considered different.

Thus, before you purchase an air purifier, you need to understand everything about square footage, activated carbon and HEPA filtration.

In this buying guide, we have discussed important aspects of air purifiers to help you make a good choice.

HEPA Filtration

High-Efficiency Particulate Arresting filtration is considered the most important technology in a high quality air purifier for smoke.

HEPA filtration allows the device to remove more than 99% airborne particles. Smoke particles, tobacco and secondhand smoke significantly reduce your indoor air quality.

Due to this, before you buy an air purifier, you need to make sure the device features HEPA filtration technology.

Square Footage

A high quality air purifier works best when it is installed in an appropriate room it is been designed to cover. In simple terms, a good air purifier is manufactured with a particular square footage capacity.

While one air purifier might work perfectly in an area of 12sq. ft. or less, the other purifier might be able to filter the air in a 500 sq. ft. area.

Before purchasing an air purifier, you need to measure the space. This allows you to look for a device with sufficient square footage area.

Air Purifier Efficiency

Air purifier efficiency is checked by how thoroughly an air purifier or cleaner captures particles. You also need to check the amount of air a device can process in a specific period of time.

In simple terms, an air purifier is considered efficiency on the basis of its ability to catch particles of different sizes and process sufficient air to improve indoor air quality.

It is important to understand that when the sieve-like action of a filter is finer, it can block smaller particles without any problems. However, when the sieve is finer, the filter clogs up with dirt quickly.

As most mechanical filters become saturated, they start catching more dust. Due to this, airflow becomes increasingly stymied. This reduces the efficiency of the air purifier.

High quality mechanical filters have a large surface area and fine sieve to maximize both airflow and dust collection. This results in better air purifier efficiency.

Filters using electrical attraction to properly grab particles are considered different. An electrostatic precipitator is a good example. Most electrostatic precipitators don’t slow down when filling up air, but their charge gets diminished by the accumulation of several particles.

These devices are considered most effective when they are completely clean, and air passes through them slowly.

How Electrostatic Precipitators Work

Dust particles are accurately measured by microns. It is worth mentioning that one micron is equal to 1/25,400 an inch. Human beings can see pollen, link and dust particles bigger than microns.

Most high quality air purifiers eliminate a good percentage of visible dust particles, which pass through the device. However, in order to be effective, an air purifier should eliminate microscopic particles too.

The high standard related to air purifier efficiency at eliminating dust particles was set by the HEPA filter. These filters are tested at their ability to eliminate smaller particles of micron size.

Most mechanical filters are unable to catch dust particles of this size. Particles of this size are more likely to be inhaled, and cause problems when they get settled in the lungs.

Recently, ULPA filters have become quite popular. They can eliminate dust particles of.micron size. However, they can prove to be quite expensive.

The American Society of Heating, Refrigerating & Air Conditioning Engineers tests the effectiveness and efficiency of a filter. Initial Staining Dirt Efficiency is the first rating.

It’s an important measurement of how the filter removes staining particles, such as allergens, grease and tobacco tar.

Average Arrestance Test is the second rating. Arrestance is the measure of ability for how well a device can remove synthetic dust, lint, hair and other large matter particles from the air.

Purchase High Quality Smoke Eaters to Breathe Clean Air

High quality smoke eaters help you get rid of cigarette and cigar smoker. Some good purifiers can also add more moisture to the air.

It prevents dryness that may cause irritation in several parts of the body.

It is worth mentioning that these devices can be quite effective for treating dry nose, skin, lips and throat.

Out of Stock

Cigarette and cigar smoke is considered to be very harmful. These days, you can choose from a wide range of smoke eaters available in the market at reasonable prices. Due to this, these devices are used for relieving many different problems, including:

When there is low quality air in your home, you’re prone to these kinds of discomforts. These problems are more prominent during dry winter months or when you’re using an air conditioner during the hot summer season.

It is worth mentioning that smoke eaters not only make sure your room doesn’t have bad air quality, but also get rid of smaller particles that are not visible to the naked eye. With these devices, you are able to prevent allergic reactions, and breathe clean air all the time.

Useful Tips

Using a smoke eater can provide you with a lot of relief. However, if these devices aren’t used properly, they may also cause some problems. While using these devices, special care needs to be taken in homes with children.

If you have children, it’s better to use small smoke eaters. Moreover, you should never allow your children to handle these devices. Most importantly, you should never place these devices near your children and pets.

If you allow a smoke eater to expel a lot of moisture, it can create unnecessary condensation on the walls. Excess water can turn into mold, and cause problems throughout your house. It’s important to understand that unclean devices can even cause bacterial growth, which promotes colds and coughs.

Therefore, you need to make sure your devices always remain clean. This allows them to function properly, and make sure your home’s air is always clean.

You should always follow the manufacturer’s instructions, and thoroughly clean the unit on a regular basis. This helps you prevent bacterial growth.

It’s worth mentioning that some smoke eaters get dirty easily and quickly. Luckily, they are among the easiest to clean.

Between uses, you should rinse out all used water. In addition to this, you should wash the filter system and bucket every couple of days during usage.

A lot of smoke-eaters can emit microorganisms and minerals in the air. Though they’re not necessarily harmful, asthmatics and allergy sufferers can experience some problems.

In case you experience any problems after using smoke-eaters, you should stop using them and consult your physician. These days, you can purchase a small smoke eater on the Internet.

Many online retailers sell these units at affordable prices. Before purchasing a unit, you should consult your physician about the type and size of the smoke eater. It will help you make an informed choice.

In addition to this, you should compare several options to choose the best device available in the market. You can easily find customer reviews and testimonials on the Internet to choose something suitable to your needs, requirements and budget.

With high quality smoke eaters, you always breathe clean air, and protect yourself against a wide range of respiratory problems. Just make sure you purchase a high quality device.

Air Purifier vs. Dehumidifier

Diffen › Home Improvement › Appliances

Air purifiers and dehumidifiers minimize allergens in the room, making it easier for those suffering from allergies and asthma. An air purifier circulates air through a filter that traps air-borne pollutants and irritants like dust, smoke and pollen. A dehumidifier sucks in moisture and reduces the humidity levels in the air, killing mold and microbes that thrive in moisture. (11ratings)

Purpose To circulate and filter the air by trapping dust, smoke and other allergens

To reduce the moisture content in the surrounding area.


An air purifier circulates air through a filter which removes air borne pollutants, like dust or smoke particles, and even pollen, which a dehumidifier cannot. An purifier may prevent mold build-up as it removes the spores from the air. However, because it cannot control humidity levels in a house, excessive moisture can cause mold to return. The video below deconstructs a humidifier to demonstrate how it works:

A dehumidifier’s primary function is to eliminate excessive moisture from the air and bring down a room’s humidity levels. While this device does not clear or filter air, it does help remove allergens, like mold and dust mites, which thrive in a moist or humid environment. With a humidity level less than 50%, these sources of allergies and asthma wither and die. This is how a dehumidifier works:

Two types of dehumidifiers are typically found in the marketplace: warm mist and cool mist. Regardless of mist type selected, both affect moisture level in the air and lower the level of humidity. Other types include:

Mechanical /refrigerative is the most common type and works by drawing moist air over a refrigerated coil with a small fan. Condensed air is collected, and is effective at higher ambient temperatures where the relative humidity is over 45%.

Air conditioners inherently act as dehumidifiers.

Electronic dehumidifier uses a Peltier heat pump to generate a cool surface for condensing the water vapor from the air. It has no moving parts and hence is quieter. But it has low energy efficiency and this design is used for smaller humidifiers.

Ionic membrane – a specialized type of ionic membrane can be used as an ionic pump to move humidity in or out of sealed enclosures at the molecular level. The device is mainly used in industrial areas with fuel cell, chemical, or water improvement application.

Makeshift – Window air conditioner units that operate similar to mechanical/refrigerative dehumidifiers. Makeshift dehumidifiers function by sending its heat exhaust back into the room.

Health hazards of Air Purifiers

Ozone production is typical for air ionizing purifiers. Ionic air purifiers can produce ozone as an additional feature to eliminate odor. Although high concentration of ozone is dangerous, most air ionizers produce low amounts (<0.05> ppm). Many air purifiers generate some ozone, and in the presence of humidity, small amounts of nitrogen oxide.

The noise level of a purifier can be obtained through a customer service department


Maintaining dehumidifiers requires cleaning all its coils and buckets periodically, and also checking these coils for frost, to improve efficiency.

Air purifiers can be maintained by replacing the filter every months. If the humidifier has plates, they should be washed once a week. To clean the plates, take them out of system and place them in the dishwasher or submerge them in the sink.
