Customer Reviews
My air is so much cleaner!
I got the adjustable gold frame filter with MERV 13 media, and wow, what a difference! My allergies have been so much better since I installed it. The frame was easy to set up for my specific size, and swapping out the media is a breeze. It's awesome to know I'm using a reusable system too, feels good for the environment. I'm telling all my family about this! Will absolutely be back for more filter media when it's time.
Solid product, slight shipping delay
I bought the Bio-Sponge refillable filter and some replacement filter pads. The system works well, and I like the idea of less waste. Shipping took about 8 days to reach me, a bit longer than I hoped, but the items were packed securely. Product quality is good for the price. I'd definitely consider buying again, maybe a bulk pack if the shipping is faster next time.
Good filters, fast shipping
I ordered a MERV 11 filter and it arrived quickly. Fit my furnace perfectly. Quality seems solid. Happy with the purchase.

Anyone know if these Air Sponge filters are actually worth it compared to like, a Filtrete from Home Depot? Seen a lot of ads but not sure if it's just marketing hype.
hey, was looking at the bio-sponge system. how often do I really gotta change those refills? i'm usually pretty bad at remembering.
