These filters are top quality and arrived quickly. I live in the TX panhandle where blowing dust is part of life. And being in the 4th year of drought hasn't helped. So a good quality filter like these helps a lot to keep the amount of dust and pet dander minimized. The price was good with the free shipping and I will buy again when needing more.

I use these as a cheap emergency replacement for HEPA filters: when stacked in series two of these 1" filters reduce the 0.3 micron particles 50-fold (98% arrest, verified with a calibrated particle counter). The 12" size is relatively standard , and fits into standard housings. These Filtretes are odour-free, unlike costly HEPA filters from certain supplies (e.g. IQAir). Now, I wish they costed less (hence 4 stars).

These filters are a premium product. I would so often forget to replace my (regular) filters because they are in the attic and out of site, out of mind I suppose. I was probably replacing my filters every 5 or 6 months due to this. Since I started buying the Bluetooth-enabled smart filters, I can check on their status without going into the hot or cold (depending on time of year) attic and I LOVE IT. The app gives notifications regarding the status of the filter life along with the status of outdoor air quality and indoor quality (if you're willing to add a monitor). I recommend this product to all my home owners as I don't know how you can be confident in your air quality in your house unless you just have reminders to replace the filters every few months. I have enough things that I have to set as reminders so I don't want any part of that process! This product eliminates that option and makes things easy since we always have our phones on us anyway.

My wife and I have been using these filters and they are great quality. We got it a great price and highly recommend
