Cleaner Air for Your Concerns

An advantage we have in selling air purifiers direct is that we talk with you. It's interesting that people buy air cleaners for a wide variety of reasons.

To help you choose we have also written guides based on the most common concerns.

Focus on Indoor Air Quality

At first, we focused on making the best HEPA filter. Clemson University did the only comprehensive and independent university study of air filters.

The Oransi HEPA filter was the only model tested to remove all airborne particles. It goes without saying this is key to having the best HEPA air purifier .

HEPA stands for High Efficient Particulate Air. A HEPA filter is the best and safest air purification for the removal of dust, pollen, and mold spores.

This is because of the high efficiency in removing particulates. It also works well with pet dander and other air pollutants. We also give you quiet, yet powerful motors to deliver high air flow and a strong CADR rating. The CADR rating is the Clean Air Delivery Rate. It represents the volume of clean air filtration.

Since then, we have expanded into chemical pollutant and odor removal. This is key to providing you with a complete indoor air cleaner.

As part of this we developed an advanced activated carbon filter. It removes not only cigarette smoke smell but also difficult gases like formaldehyde. It also does well with odors and volatile organic compounds (VOC's).

The best part is we give you indoor air purification that is safe and ozone free. We do not sell ozone generators given the health issues related to ozone indoor air pollution.

HEPA (and better than the HEPA standard) filtration coupled with advanced activated carbon filters is the air purification technology we use in our EJ Air Purifier and Erik 650A air purifiers. The EJ has a true HEPA air filter and the Erik650A's main filter is closer to an ULPA filter rating. We are proud to export our made in USA air purifiers to Asia to help with the air pollution issues there.
