It surprises many people that indoor air pollution levels are very often much higher – up to five times – than outdoors even in metropolitan areas. Part of the reason for that, barring having a smoker in the home, is that modern homes are designed and built for minimal air exchange in order to meet strict energy-efficiency standards.

waterOpening a window or two to let in fresh air may not be possible if the weather is cold outside. Even if you could open the windows, that will never be enough to truly clean your home’s air of nasty pollutants such as pet dander, mildew, mold, pollen, dust mites from your carpets and airborne microorganisms. Besides those, only an air purifier can relieve your home from the unpleasant odors created by smoke, cooking and volatile chemicals in paints, plastics and cleaning products.

Quality air purifiers make a tremendous impact on your home’s indoor air pollution. Many people think they are only a smoke filter. Some products are aimed at being the best air purifiers for smoke.

However, all the air purifier reviews here are for products that do so much more. They use multiple stages of filtration, sterilization and air treatment to obtain the freshest, cleanest indoor air imaginable. Asthma and allergy sufferers especially appreciate the relief they get from running the best air purifier for only a few hours.

We have spent hundreds of hours compiling detailed reviews of the best air cleaners on the market plus guidance on how they work, how to maintain them and how to choose the best one for your family.

If you want to get right down to business, we also have the following comprehensive comparison chart containing our recommended air purifiers. Use it to quickly select the best air purifier for cigarette smoke or any purpose and start breathing easier right away.

How to Get Rid of Cigarette Smell in the House

Once the smell of smoke permeates a home’s walls, drapes and furniture, it can be difficult to remove. The best air purifier for cigarette smoke can greatly reduce the smell from a previous occupant who smoked, but to totally eliminate it try these methods:

  • Sprinkle baking soda on all fabric surfaces including drapes, carpets and furniture. Let it stand for a day, then vacuum it up.
  • Non-fabric surfaces should be cleaned with white vinegar and warm water. Use bleach and water on hard, non-porous surfaces such as tile, bathtubs and vinyl.
  • If the smell persists, you may have to re-paint the walls. Clean them with TSP followed by a deodorizing primer such as Kilz before the finish coat.

If you move into a smoke-free home or have cleaned out the smoke smell by the above methods, purchase a top-quality air purifier to eliminate any lingering scent. Even if you or a family member smokes in the house at this point, a top-rated air purifier with at least four filtration stages will significantly reduce or eliminate new smoke odors. Naturally, it also eliminates many other unpleasant odors so that your home will smell like new again.

This tower air purifier from Alen is so compact and lightweight that many buyers take it with them traveling. If you have ever spent the night in a so-called “non-smoking” hotel room, you can understand why. It has all the usual controls and indicators of most air purifiers including a 3-speed fan button, filter change indicator, LCD display and a 12-hour run timer.

It comes standard with a HEPA-Pure filter, so if you want to customize it, you have to buy an extra filter. A few buyers have thought it too noisy on the highest fan setting, but then few people use that setting as the unit performs admirably with lower flow rates. One thing to note is that it uses a “HEPA Type” filter that cannot filter higher than 95 percent of 0.3 micron particles. Other purifiers in this guide use a true HEPA filter.

Conclusion

The Alen T500 is one of the lightest and smallest air purifiers you can find, but its performance belies the first impression that it is under-powered. With a respectable CADR of 159, it easily refreshes the air in a bedroom or hotel room quickly. You can configure it to emphasize removal of allergens, germs, smoke and odors via custom Alen filters.

Four-stage filtration with true HEPA filtering under $100 is a great deal. Albeit, this model is sized for an average bedroom or small living room, but it does a great job at reducing the allergen levels in your entire home. This is the best air purifier for smokers who want to keep the indoor air smelling fresh.

The operation is dead simple with just a 3-speed fan control to operate. There are two alert lights. One goes on when it is time to change the filters and another indicates it is time for a new UV-C bulb, which runs about $30.

Air purifier reviews are overwhelmingly enthusiastic about how much their indoor allergy or asthma symptoms are reduced within a short time after turning this unit on. Most find they never have to turn the fan up all the way, so they enjoy the quiet operation.

Conclusion

The GermGuardian 3-in-1 air purifier provides a stylish and quiet way to add fresh air to your living areas with four special-purpose filters plus a UV-C sanitizing stage that kills airborne viruses and bacteria. It is simple to operate and maintain and for under $100 represents one of the best values in air purifiers.

The Fellowes AP-300PH is an affordable solution for maintaining fresh, odor-free air in a large room or office. Air purifier reviews often cite this model as the best air purifier for smokers. Although one or two buyers have noted a high-frequency chirping from the ion generator, the vast majority of air purifier reviews applaud its quiet efficiency. The auto-adjust feature works extremely well to maintain constant air quality even if someone lights up a cigarette.

You always have manual control over the fan speed from Low to Turbo if you think it is too noisy or want to boost its exchange rate. Separate alert lights tell you when it is time to change either the HEPA or carbon filter. This is a relatively small, unobtrusive, quiet, set-it-and-forget-it air purifier that provides clean air for many years.

Conclusion

If you have pets, a smoker or are sensitive to dust or other allergens, this Fellowes 300 square foot capacity air purifier is just the appliance to clear the air 24/7. It adjusts to your air quality automatically, runs whisper quiet and comes at a very affordable price.

The AeraMax 300 is distributed by Fellowes. Although it claims a room capacity up to 600 square feet, it has a similar CADR as the Fellowes AP-300PH reviewed earlier. It is more stylish than the AP-300PH, a bit quieter, but functionally is very similar.

It indicates air quality with three different colors of light from red for poor quality to blue for good quality air. You can override the fan speed manually instead of relying on the automatic sensor, however. One additional feature the AeraMax 300 has over the AP-300PH is that you can manually turn off the negative ion generator. There is a lighted blue star button near the bottom to do this. If it is lit, the ion generator is working. Press and hold it for three seconds to turn it off.

Conclusion

The AeraMax 300 is an ideal size air purifier with 4-stage filtration for large rooms up to 600 square feet. It senses and adjusts to indoor air quality automatically. It has a clear display and intuitive controls for easy operation. The cost is slightly more than the Fellowes AP-300PH but is similar in operation and capacity.

AHAM certifies this air purifier for rooms up to 390 square feet, but with a 250 CADR rating and circular intake design it has extra capacity. This design makes it the best air purifier for cigarette smoke in larger rooms.

You can tell from the quantity of buyer reviews on this Honeywell model that it is an extremely popular purchase. That is probably due to its exceptional dollar-to-CADR ratio. It has two minor drawbacks, which are the fan noise and its high power consumption. Even on the lowest fan speed, it draws about 50W. Otherwise, purchasers are pleased with its ability to create fresh, allergen-free air in a hurry.

Conclusion

This air purifier has fewer bells and whistles than comparably-sized models, but it makes up for that with a high air-refresh rating and a long-life HEPA filter. It is ideal for extra-large rooms and is available at an attractive price.

The Hoover 600 has a CADR of 51 and is rated for 79 square feet, so this purifier is adequate for a small bedroom, although many buyers use it successfully in a larger space. It may not be the best air purifier for removing smoke smell due to the lower capacity.

It does have a 4-stage filtration system plus UV sanitation going for it, however. It runs quietly even on the highest setting and the washable pre-filter is a nice convenience that enables subsequent filters to last longer. The super-bright blue backlight could keep some people up at night. One annoyance noted by a few buyers is that there is no settings memory. Each time you turn it on, it defaults to fan speed 2 with both UV and ion generation on.

Conclusion

The Hoover 600’s tall tower design takes up little floor space and puts the top-mounted controls at a handy height. For a small bedroom, this is an ideally sized purifier with multi-stage filtration and easy-to-use controls.

5. Winix WAC5500 True HEPA Air Cleaner with PlasmaWave Technology

You can leave the Winix WAC5500 on auto-sense mode and it will automatically adjust its cleaning power according to a five-point scale of surrounding air quality.

HEPA filters are not cheap. They usually run around $30 and up and typically need replacement once a year. So, the Winix 5500 washable filter is a boon to its maintenance costs. You should clean it twice a year. Under normal usage it lasts three years. It is a very sensibly priced machine for the capacity and impressive CADR rating. That makes it one of the best air purifiers for smoke.

There may be a quality problem with the PlasmaWave ion generator as a few buyers report an irritating high-pitched squeak from it after several weeks of use. Otherwise, the Winix 5500 gets quite good ratings and is a popular air purifier. The auto-dimming “sleeping” mode is a nice touch as it lowers the LED light levels at night, which is a big plus if you prefer sleeping in darkness. Overall, this is a decent air purifier at a decent price that makes lots of fresh air in a large family room or living room easily.

Conclusion

The Winix 5500 is a step up in capacity and features from Winix’s 5300, which is being discontinued. It will clean the air in a large 350 square foot or larger room with minimal power consumption at a very low noise level. It sells for less than half the manufacturer’s price on Amazon, so is a true bargain.

How Does an Air Purifier Work?

Air purifiers are designed to remove the smallest pollutants, even down to the molecular level, from your home’s indoor air. They accomplish this via different filters and processing steps from three up to six stages in total. Some of these stages physically trap pollutants, some interact and neutralize pollutants at the molecular level and some kill airborne pathogens with UV radiation.

All air purifiers share the same fundamental design in that they use fans to both draw the dirty air in and push clean air out after the filter stages. Clean, purified air is expelled from the machine from the top or sides. The amount of air that can be cleaned depends on the volume of air that the fans can move per minute through the purifier.

Here’s a video that shows air purifier working principle:

Each filter stage is designed to remove specific kinds of particles with some overlap between them:

  • Pre-filters physically trap the largest particles such as lint, hair and house dust.
  • Activated carbon filters act as a smoke filter and also trap molecules from volatile chemicals and cooking odors. They do this via molecular interaction with the surface of the carbon.
  • True HEPA filters are made from extremely fine media that trap the smallest physical particles down to 0.3 microns in width.
  • Electrostatic filters trap small particles via static electricity, which causes the particles to adhere to metal fins.
  • A UV-C lamp stage irradiates bacteria and viruses rendering them harmless.
  • A negative ion generator stage does not directly filter the air, but the ions it produces neutralize odor-causing molecules in the room air.

All of these stages work together to produce the cleanest, freshest air possible in your home.

How to Choose the Best Air Purifier for Smoke

Choosing the best model of air purifier is mainly an objective process of checking off the presence of key features. Buyer reviews can be used to validate how well specific features work.

Filtering Technology

A good place to start your research is to understand how an air purifier works and the types of filtering or cleaning stages it utilizes. In general, the more filters the better. At a minimum, a good air cleaner has at least an activated carbon filter and a true HEPA filter. The best air purifier for smokers will also include a negative ion generator, which is not strictly a filter but an air quality improver. The very best purifiers also employ a pre-filter, UV-C sanitation and the ability to add custom filters for your specific air quality situation.

Room Size Capacity

girl in a room with air cleanerEven the best air purifier for smokers will not do its job adequately if it must clean more air volume than its rated capacity permits. Most air purifier manufacturers list in their product specs the size of room for which the purifier was designed, but this can be misleading. The scientific measure of capacity is CADR, which stands for Clean Air Delivery Rate and designates the cubic feet of clean air per minute that the machine delivers.

To calculate the CADR you need, multiply the room’s square footage by 0.8 if you have standard eight-foot ceilings. A 12 x 10 bedroom needs a minimum CADR of 12 x 10 x 0.8 = 96. In short, a bigger CADR indicates a more powerful air purifier.

Many manufacturers list separate CADR ratings for smoke, dust and pollen. These are usually close in value, however, so when you see a single CADR, just use that. Also, keep in mind that not everyone has equal sensitivity to indoor pollution, so in some cases you can get good results in twice the floor area as the product specs state.

Versatility and
Convenience

The more fan speed selection you have the easier it is to set your air purifier to the most efficient setting. As fan speed increases, more air is cleaned. However, the sound level also goes up and if the air quality is already good, you are simply wasting energy selecting a high fan speed.

The best air purifiers have auto-sense technology, which indicates to you via lights or symbols what the current air quality is. These clean air machines automatically adjust the fan speed to correlate with that quality level.

Top rated air purifiers add other levels of convenience also. Some have “sleep” modes that dim their indicator lights in accordance with the ambient lighting so that you can sleep without bright lights shining in the room. Others have adjustable timers so that you can set it to run for several hours while you are away.

Additional Criteria

air purifier filtersAn air purifier for smokers or those with asthma or allergies should have the most filtration stages possible and have the possibility of selecting custom filters for later stages that remove specific pollutants. For instance, the Rabbit Air MinusA2 offers four different custom filter options.

A final criterion is price. However, you should not over-emphasize this, since even the very best air purifiers are usually under $500. Given the comfort they bring and the many years they last, even the most expensive machine is relatively inexpensive on a day-to-day basis.

Air Purifier Maintenance

Air purifiers sometimes need a little TLC to keep them running at peak efficiency. Fortunately, all of the air purifiers covered in this guide are easy to maintain.

If your unit has a pre-filter, these are usually washable. Simply remove the outer housing cover and peel off the pre-filter if it does not have its own frame. Wash it in a mild solution of detergent and lukewarm water to remove any collected dust or other debris. Be careful not to tear it. Alternatively, you can gently vacuum collected dust from the pre-filter. Clean the pre-filter once a week.

If your unit has a carbon filter and a HEPA filter, these are changed at regular intervals of three months and one year, respectively. Most units have separate LED indicators for each of these filters that light up based on the amount of time they have been operating. Washing them is ineffective and could even damage them. The only exception is the washable HEPA filter in the Winix WAC5500 air purifier that we reviewed earlier. You should follow the manufacturer’s instructions for cleaning that filter and remember that it must be replaced after six washings.

Air Filter vs. Air Purifier

air cleanerYou may have heard the terms “air cleaner” and “air purifier” used interchangeably and, in fact, they are essentially the same thing. Some people make a distinction between those two terms by referring to air cleaners as machines that use filters to remove particulate indoor pollutants and air purifiers as machines that remove pathogens such as bacteria and viruses. Since the air purifiers presented in this guide perform both those functions, we make no distinction between the terms, but prefer to call them air purifiers to avoid confusion.

However, air filters and air purifiers are indeed different mechanisms for improving the quality of your indoor air. Air filters are far simpler and generally less effective than air purifiers. If you have an HVAC system in your home, you already have an air filter. It is likely located inside the housing of your furnace or air conditioning unit. It is a thin rectangular panel around 20 by 20 inches and supports some type of filter medium.

Although these panels can be purchased with very fine filter media, their main purpose is to remove the largest particles of dust, lint and hair to protect the HVAC system, which does help clean the home’s indoor breathing space somewhat.

Air purifiers on the other hand are designed to remove particles as small as 0.3 microns as well as remove pollutants at the molecular level such as VOCs, smoke and odors. Obviously, they are the best air purifier for cigarette smoke, especially compared to air filters. They typically have additional stages that also kill bacteria and viruses and emit negative ions that bind to, say, odor molecules to deactivate them or make them filterable.

  • Inexpensive
