CAL20 TI 20x25x5 Air Filter - Ultra Low Pressure Drop - The Most Energy Efficient MERV 16 HVAC Filter - Annual Replacement - (Actual Dims: 19⅝ x 24⅝ x 4⅜in)

I love this product! What really makes this filter stand out is its high dust holding capacity which means less frequent replacements for me to do. It also has a low pressure drop which makes it more energy efficient. And, it is rated at the highest MERV rating available (MERV 16) which is pretty much a hospital-grade filter! I feel comfortable knowing I have a low maintenance, energy efficient and highly effective furnace filter cleaning the air in my home! I highly recommend this filter!

We had Breathable clean our air duct two years ago and they installed the Breathable filter. The filter is easy to install and does a great job. The house air quality is good and easy to breathe. Every time we heat or cool the house we know the air is being cleaned. We are less reliant on our portable air purifiers. Highly recommend their service and product!

Durable and easy to install, this is I think our 3rd set and we've been really happy with them. Our family suffers from allergies so important to us to have good filters

We've been very happy with the performance of this air filter. We had Breathable clean our ducts and install this filter last year, and it's made a big difference in indoor air quality. No more smelly furnace air when starting up, and anecdotally it seems like we have less dust around the house when our furnace is running frequently during the winter months. While it definitely costs more than regular furnace filters, it doesn't need changing as often: 1x a year compared to swapping the typical ones every few months. Our indoor air is cleaner, and our allergies aren't as bad. Thanks for helping us breathe more easily!

i've been using the breathable hvac filter for 5 years in my home and love it. it's a very high quality filter and lasts a very long time compared to the cheap ones at the hardware store. thank you for making a great product!

Product seems good, well constructed. 8Only complaint is shipping which didn't provide additional packaging so it arrived with a hole that went thru the box and tore inside the plastic bag containing the filter. Filter looks only slightly impacted but still useable.

For residential HVAC air filtering, this is the best filter you can get. We bought ours last year and are so happy we made the change.

We’ve been using the Cal16 filter for two years now and it has made a dramatic difference with our house air quality. The filters are easy to install and are the most effective product that we’ve tried. Other filters that we’ve tried (of much lower quality) do not work and end up costing way more in the long run. I would highly recommend these filters; we will not buy another product.
