4000 DS Air Purifier AllerAir The Allerair 4000 DS air purifiers feature a unique tar-trapping pre-filter that grabs larger particles and tar, which also extends the life of the HEPA filter. The unit features a micro-wrap filter to deal with small particles as small as the fine cigarette ash and a 3" extra-deep 16 pound carbon bed that increases dwell time, allowing more chemicals, gases and odors to be absorbed. This is the only proven method of adsorbing lingering substances that result from smoking tobacco in a closed environment long after active tobacco has ceased.
