Seems like a great filter, fit well.
It’s still in the box. I had just changed filters prior to ordering. Arrived in good condition and looks like it will work.
The only place I shop for filters. Highly recommended!
I love the convenience of getting the air filters delivered on schedule!
I learned about these filters at a farm conference and immediately subscribed. As a farmer, it’s important to support products made from what we grow.
So far good filter
Noticed a quick improvement in air quality in the house after replacing my filter. It's also great to have my next air filter coming without having to think about when to go to the big box store to get the replacement. I also breath easier knowing no harmful chemicals are in my filter. Great price and free delivery too
excellent product! Very happy
Well made and fast shipping
Nice product, well constructed and durable. Look forward to seeing results after usage.
Luv them
So far they seem good. I have only been using for a couple weeks
Looks like they will work.
It first well. I just use it for few days&
Great product, especially at the discounted price. Renewable, made from corn, from a US based company! Keep up the good work!
