Customer Reviews
Bio-Sponge system works well
I decided to try the Bio-Sponge refillable air filter system for my home. The initial order included the adjustable gold frame filter and a pack of the polyester filter media refills. Measuring my furnace for the frame was straightforward using their guide on the website. The frame itself felt sturdy and adjusted easily. Installation was simple enough, and replacing the filter media every few months is quick. I've noticed less dust around the house since switching. My only small suggestion would be clearer instructions on disposal of the used media, but overall, it's a smart system that saves money and seems effective.
Good quality, minor shipping hiccup
I purchased a custom size air filter and some replacement filter pads. The filter itself is well-made and fits my HVAC unit perfectly, which is great because custom sizes can be tricky. Shipping took about a week, which was a little longer than I expected, but it wasn't a major issue. Packaging was secure. Overall, satisfied with the product quality and value, just a note on the delivery time.
Always reliable filters
I've ordered from Air Sponge several times now. My last purchase was for a 6-pack of MERV 11 pleated filters. Just like before, they arrived quickly, in about 4 days to my house in Florida. The filters fit perfectly, and the air quality always feels better. Consistency is why I keep coming back.
