Airpura T400 air purifier covers 1000 sq ft (depending on model and speed) and is specifically designed for tobacco smoke and to remove 4000 chemicals, tars and gases found in tobacco smoke. The impregnated carbon bed adsorbs over 4000 harmful chemicals, gases and at least 60 carcinogens.
If you loved the larger T700, then you will love the newer G400DLX models designed for smaller spaces.
Airpura T400 air purifier is specifically designed for tobacco smoke and to remove 4000 chemicals, tars and gases found in tobacco smoke. Covers up to 1000 sq ft depending on model and speed. The deep carbon bed adsorbs over 4000 harmful chemicals, gases and at least 60 carcinogens.
Please note: As of 2021, the gaskets are now neoprene.
Recommended to have 10-12 air changes an hour for a heavy smoke area.
A HEPA-Barrier is used in Airpura's C and DLX models. The HEPA-Barrier is 95% at 1 micron since the space is predominantly used for carbon for VOC, gases and odor adsorption. The C and DLX units focus primarily on VOCs, gases, and odors, instead of ultrafine (.3 microns) particulates like a True HEPA canister. A True HEPA Canister is 99.97% effective to .3 microns.
The T700 uses a HEPA-Barrier, not a True HEPA so it filters to 1 micron, not .3 micron, but is stronger for VOCs, odors, and gases.
Estimated Maintenance:
Pre-filter |
TarBarrier varies by usage about monthly for public places and less frequently for residential use |
Activated carbon | 2 yrs max depending on usage & contaminants |
HEPA-Barrier |
T700- Every Time Tar Barrier is changed in public place |
*Note: All filter maintenance is based on standard usage and average contaminants. Depending on the specific situation, filters may need changed more or less frequently.
Technical Specs:
If the T700 is too large, the T400 is an excellent option.
Ideal for Smaller Spaces:
These are just some of the uses of this unit. Many contaminants fall into more than one unit so if you\'d like assistance finding the best unit for your needs, please contact us.
Also keep in mind that numerous factors come into play when considering an air purifier such as but not limited to the contaminants, coverage (sufficient air changes for the level of off gasing), speed of off-gasing, particulate matter, sensitivities of the consumer and much more.
The usages shown above are simply suggestions. Air Purification is not a black-and-white science. There is a lot of gray area that affects the results such as things that are out of our control like humidity or even the location of the unit. I wish there was just 1 unit for every need, it would make our job much easier, but there are trade-offs like sound for power and budget for filtration.
Don\'t hesitate to ask especially if the contaminant is high.
Superior Dwell Time: The 395 CFM impeller/motor combined with the variable speed control and unimpeded airflow of the Airpura 400 series allows the airflow to be set precisely and achieve maximum results.
The 4-series allows our clients not only to enjoy the same high-quality filtration as the 7-series configurations but just in a smaller, compact unit.

Download Airpura Activated Carbon Adsorbancy Ratings. Please note this is for standard activated carbon for common chemicals and VOCs. This list does not list everything tested so if you have questions, feel free to contact us directly so we can check with the chemist. Any unit that uses impregnated carbon such as but not limited to C400DLX,C400DLX, V400, F400, F400DLX etc., would have higher adsorbancy ratings.

Estimated Maintenance:
Pre-filter |
PreFilter varies by use but is typically changed every 6-12 months. TarBarrier varies by usage about monthly for public places and less frequently for residential use |
Activated carbon | 2 yrs max depending on usage & contaminants |
HEPA-Barrier |
HEPA-Barrier Every Time Tar Barrier is changed in public place or yearly typically for residential use. |
HEPA or SuperHEPA | 2-5 yrs max depending on usage & contaminants |
*Note: All filter maintenance is based on standard usage and average contaminants. Depending on the specific situation, filters may need changed more or less frequently.
