On top of every day foot traffic by humans, we have three dogs, and we were going through filters almost every week.I've been making efforts to reduce my family's carbon footprint, and was happy to find these, and when they arrived, I can't tell you how pleased I am that they were so sturdy.It's been 3.5 months, and, again. So thankful for this product.Make sure you buy two. ### ⭐⭐⭐⭐⭐ Works better than I thought it would *by C***. on Reviewed in the United States on August 7, 2017* Works better than I thought it would, better than the basic dust Filtrete Filter.

I bought a second one to use while washing my first one. ### ⭐⭐⭐⭐⭐ Been using permanent HVAC filters for 8 years. I ... *by L***G on Reviewed in the United States on April 1, 2018* Been using permanent HVAC filters for 8 years.

I have 2 sets. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/29951477-14x20x1-washable-permanent-a-c-furnace-air-filter](https://www.desertcart.co.za/products/29951477-14x20x1-washable-permanent-a-c-furnace-air-filter) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-23*
