Rainbow E Series HEPA Exhaust Filter

No, this specific exhaust filter is engineered exclusively for the Rexair Rainbow E and E2 series vacuums. It will not fit older Rainbow models or other vacuum brands.

While the filter is washable, you should only clean it when you notice a significant buildup of dust or a decrease in airflow. Always ensure the filter is completely air-dried before reinstalling it into your vacuum to prevent mold or damage.

Choosing a genuine OEM part ensures the filter meets the exact material and airflow specifications of your Rainbow system. Generic filters often lack the precise fit required to maintain the vacuum's seal, which can lead to air leaks and reduced filtration efficiency.

Yes, this is a HEPA-grade filter designed to trap fine particles, including common household allergens like pet dander, pollen, and dust mites, helping to improve the air quality in your home while you vacuum.

If you notice a musty odor while vacuuming, a visible buildup of dust on the filter that doesn't wash away, or a noticeable drop in suction power, it is likely time to replace your exhaust filter.
