Details
Original OEM factory True H13 class Medical Grade HEPA filter (Neutralizer) for the single speed E-2 (e SERIES™) Rainbow unit. If you have to remove four screws to replace your filter, this is the WRONG PART!
Click here to go to correct part.
A good policy is to replace your filter once every 3 years if you are using a factory original Rainbow filter.
(Generic filters list that you should replace theirs every 6 months.)
Effective serial number 9280000 with a start date of March 27th 2000 through serial number 9999999 and an end date of September 3rd 2003.
The bulk item number for this is R12106B. Some websites list this part number for a single item which is incorrect.

Here is a link to more information about HEPA filters and the fraud within the filter industry...Wikipedia
The NY Times post in their article "Can HEPA Air Purifiers Capture the Coronavirus?" explaining the use of a TRUE HEPA and reduced speed similar to a low speed air filter.
They reference a study done by NASA "Submicron and Nanoparticulate Matter Removal by HEPA-Rated Media Filters and Packed Beds of Granular Materials" which states "...where decreasing the velocity by three-fourths reduces the particle penetration over three orders of magnitude with a corresponding efficiency increase from 99.998% to 99.99998%. In other words, a simple HEPA-rated filter will perform as an ULPA-rated or better filter by simply lowering the flow velocity through the media."
It is better to toss your old filter and not replace it than to buy a generic filter. Generic filters do very little for the air quality while reducing your airflow and performance.

We ordered 2 parts on the website, then, after the order was placed, noticed something about needing a HEPA filter - who knew? So we immediately called them, learned that indeed we did need this part, and they added it to the order. Plus our agent stayed on the phone while she taught us where to find the filter and how to replace it. Great customer service!!

The motor is noticeably Quieter, not pushing Air against a dirty filter.

Did a small rebuild of my ancient rainbow. All parts works beautifully. Online videos clarified how to disassemble. Maybe I will live long enough to outlive this machine????
