Review on 🌬️ Filtrete Ultimate Allergen Reduction All Over by Jack Bhowmik

Excellent Filter. I work in HVAC and work with different types of filters. In my opinion this is the best you can buy in the 1 inch category. It fits snugly against the filter grilles, keeping air out of the sides. However, it's not so tight that you have to pinch it to get it in place. It doesn't bounce up and down while the system fan is running. The extra pleats provide significantly less static pressure, which extends the life of the fan motor, but also allows for more airflow when properly filtered. We recently had a rainstorm and my roof collapsed. The filter is completely black. I thought it was due to too much moisture in the air, but it turned out I had a lot of black mold when the roof came in. I believe the blackness in the filter was actually mold spores. I've never seen a filter go black in a couple of hours. I change the filter every 2 months and my fan runs about 30 minutes. every hour. It helps to purify the air in the house to a great extent. Combine this with an air washer that uses a mix of UV and a honeycomb matrix and you have hospital quality air as well as a very hygienic home. The investment in these filters is high, but replacing your HVAC system is even higher. I would highly recommend these wonderful filters and will only be using them until I upgrade to a 5 inch filter.
