Check On Amazon Notes To Choosing The Best Air Purifiers for smokeHere are 2 factors to be aware of when choosing the right smoke air purifier.1. The Best Air Purifiers Have True HEPA Air FiltersAs a general guideline, air purifiers with True HEPA filters are the best in terms of removing common air pollutants like dust, spores, pet dander, pollen and smoke particles. However, most smoke particles are too microscopic even for a True HEPA filter. The carbon pre-filter is responsible for most of smoke filtration. Smoke chemically reacts to and gets absorbed by the carbon pre-filter in air purifiers.So having a True HEPA air purifier is not necessarily important for smoke removal. That said, the most powerful and best rated air purifiers for cigarette smoke are also True HEPA air purifiers, simply because high quality air purifiers feature True HEPA filters. You may not always need to go for a True HEPA air purifier, though. For really small rooms, a compact machine like the Honeywell Compact Purifier HHT-011 is often sufficient.2. Clean Air Delivery Rate For Tobacco Smoke (CADR)CADR, or Clean Air Delivery Rate, is an industry standard measure for air purifier performance. The CADR Tobacco Smoke rating range from 10 to 450. The higher the rating, the faster the air cleaner can purify smoke effectively.Air Purifier Guide for Smokers: How To Find The Best Air Purifier for SmokeSometimes, the weather gets too hot or too cold that you’ll be forced to smoke indoors. Some family members or even neighbors may be offended by you for turning the garage into your personal ash tray, but much of this can be avoided with a good air filter to take care of that smell. There are many air purifiers out there that can take care of the cigarette/cigar smoke, but before you go out to buy one, consider the following factors explained below.See a list of the best air purifier for smoke according to room size and smoke filtration ratings. Room SizeThe first factor that determines the best air purifier for smoke to purchase is to fit it to the size of the room where the air purifier will be placed. A bedroom for example would require a purifier that has lower noise levels. A small room would require compact-sized air purifiers, while large rooms would need the more expensive types that can purify large volumes of air. As a tip, measure the room’s dimension and buy one that is rated according to that dimension, if not higher. Most air purifier efficiency ratings are based in average-sized rooms. So you better get that number ready when purchasing one.Also, some large air purifiers will also take up room space. You don’t want to end up with large purifier that takes up a quarter of the room space, right? A larger room may require a powerful air purifier like the Whirlpool Whispure, while a small home office may just need a desktop odor eliminator.Certification Ratings: Clean Air Delivery Rating CADRFor air purifiers, CADR (Clean Air Delivery Rating) is a rating given to air conditioning appliances (air purifiers included) by measuring the volume of air it is able to purify in a minute inside a 1008 square ft room size. When looking for CADR look at the product packaging. The CADR has 3 numbers representing smoke, pollen and dust. We want CADR numbers that are higher because this means that the unit you’re buying can filter at a higher pace.The best air purifier for cigarette smokers is one with CADR for smoke that is rated at least 2/3 the recommended room size.Type of Filters UsedFor cigarette smokers, a combination of HEPA (High Efficiency Particulate Air) filters and carbon pre-filters are ideal. The most ideal though are air purifiers that include a carbon pre-filter that helps extend the life span of the HEPA filter. The carbon pre-filter removes large particles from the air before they pass through the two other filters. At the same time, they will also absorb smoke odors, something that HEPA filters alone cannot accomplish.A HEPA filter is capable of removing the small particles from the air (0.3 microns in size) and is ideal for removing dusts and air-borne ash from the cigarette that was able to pass through the pre-filter. Carbon filters use the activated carbon to remove odors and air-borne chemicals in the air such as cigarette smoke and paint fumes.There are purifiers that are out in the market that does not use filters. These purifiers use ionizing agents and ozone purification to eliminate smoke odors. Ionic filters too are good for removing smoke from the air.Filter Availability & CostWhen scouting for air purifiers, make sure that the filters for replacement are easily available. Most air purifiers intended for cigarette smoke use carbon and HEPA filters. Carbon filters lose their efficiency to absorb smoke odor over time, so they require replacement. Some HEPA filters are replaced but some can be reused by removing the particles trapped by vacuum. Carbon filters are not to be reused.HEPA filters can last up to 3 years when used occasionally, except for long life HEPA filters that could last 5 years or even longer. Carbon filters usually last about 3 months or more with regular use. Most manufacturers recommend changing them out every 3 months Remember, frequent replacement of filter requires cost and the hassle or re-ordering, so you should also consider filter life span when buying an air purifier. If you smoke frequently, then you have to replace the filter more frequently. So be sure to factor this cost in.Now that you have understood the different factors to be considered, take a look at this list of the best air purifiers for smoke. A combination of HEPA and carbon filters are ideal for air purifiers. You can research and buy these extra filters online to save money.
