Review on 🌬️ Ultimate Air Filtration: AIRx HEALTH 20X20X1 Pleated Filter for Enhanced Indoor Wellness by Keith Aluguvelli

These filters work well. They are small to begin with. Most filters that say 20 x 20 x 1 are 19.75 x 19.75 x 0.75. They are smaller in size 19.50 x 19.50 x 0.75. While it may seem like a small difference, that quarter inch now leaves a gap in my airflow that foreign matter can easily fly through. It's not that big of a deal for individual filter inputs, but for a duel it creates a half-inch of space for your filters to pass through, and it also produces a whistling noise (at least it did when my AC was on). What the filters cover, however, it does quite well. I don't recommend leaving them for the full 3 months as I changed mine after 2 and they expired. Of course, I live in the Las Vegas desert and have a lot of animals, so take that previous statement with a grain of salt. While they are technically good at blocking the airflow they can block, I would find another company that is better suited to the airflow space you are trying to filter e.g. B. Honeywell or even a mail-in-subscription filtering service. Hope this helps you!
