Q: What does the plus mean in the Biosponge filter with the blue writing on the from compared to the one I got last time with the green writing..?

Asked by: Gary - 9/1/2017
A: Biosponge with the green writing is a 30-60 day filter and Biosponge Plus with the blue writing is a full 60 day filter. They are manufactured the same but Biosponge Plus is woven denser so it will hold more, but can be restrictive if not changed in 60 days of use, Biosponge is a little more forgiving over time.

Q: Unfamiliar with bio sponge filter. Getting a new AC for the condo. Tell me are they washable, or how often to they need to be replaced? I know nothing,,,,,please help? How pricey are they?

Asked by: mary - 4/25/2021
A: The filters we offer are not washable, as washable filters are a breading ground for mold and mildew. The frames are custom made to the exact size you need and you keep using that. You just need to order the refills to change out when required. This page is for refills, you want to look on the site for AirTeva Custom Filters for the whole system. The price varies on your configurations, but honestly not more then what you can buy in the stores for cardboard filters that are doing nothing for your filtration needs.

Q: Hello. I want to order air sponge refills for my custom furnace filter (original frame) and was looking at the possibility of adding a carbon filter to eliminate odors. My question is can my original frame fit both, the sponge and the carbon filter? and if so how should they be placed inside the frame. Thank you

Asked by: Omar J Morales - 5/16/2021
A: Yes, you can use the carbon insert with your Biosponge Plus material. The carbon is about 1/8 of and inch thick so it will go into the frame first and then your Biosponge Plus refill on top.
