High-quality air purifiers with activated carbon help immensely with both cigarette smoke and odor. While eliminating the source of smoke is the best method of maintaining clean indoor air, HEPA air purifiers can greatly reduce smoke and second hand smoke in our living space. The key to effectiveness is HEPA style filtration to capture smoke particles and activated carbon to get rid of the odor.


There are 7 classes of filters for purifying both indoor and outdoor air based the percentage of particles it filters. These are - N95, N99, N100, R95, P95, P99 and P100.


There are 3 proven strategies to improve air purifier for smoke.


1. Source control - This means to remove the source of the issue. If we can completely remove the source then there is no need of air purifier.


2. Ventilation - Another option is to improve ventilation in our home or work space. This is a good option if we have volatile organic compounds or gases, easily become a gas or vapor.


3. Air Cleaning - The third option is to use an air cleaner, if we are unable to remove air from the source, as stated in the first point.


There are mainly 6 types of air purifier.


a.      HEPA Air Purifier - The most popular type of air purifier is the HEPA air purifier. It has an efficiency of 99.97% or better in removing particles of size 0.3 microns or larger.


b.      Ionic Air Purifiers – These use charged plates to collect dust. This works like a TV screen that has a static charge and has dust on it.


c.      Electrostatic Precipitators – These work similar to ionic cleaners. They use an electrical charge to remove pollutants from the air.

d.      Ozone Generators – These exist for the sole purpose of creating ozone. They are now used for commercial purposes in controlled environments.

e.      UV Air Purifiers - An air purifier that has a UV-C light is considered a UV air purifier. UV-C lamps are commonly used as a sterilizer and in places where there is standing water to prevent mold growth.

f.       Air Scrubber – This is another type of commercial air purifier.


Alpine Repair Air Purification System is one of the most advanced one. It utilizes both activated oxygen and negative ions. It can oxidize the molecules which cause odors that could contaminate indoor air and aggravate allergic reactions such as sneezing, sinus and ear irritations, asthma and itchy eyes by significantly reducing chemical gases, paint, fumes, tobacco smoke, fungi and mold. They also remove any pet odor and dander.


Thus, negative ions in an air purifier can be created around the clock to keep down dust and particulate. The activated oxygen has a separate control. Activated oxygen is normally kept at modest levels in occupied spaces. To remove major odors, the unit may be adjusted to a higher level for a period of time.
