AllergyZone furnace and air conditioning filters are recommended by allergy and asthma physicians and proven effective in a Healthy Home study, supported in part by The Department of Housing and Urban Development (HUD). The study demonstrated a decrease in asthma related symptoms (wheezing and cough) when HVAC systems were serviced and an AllergyZone was installed. Another real-world study confirmed capture of animal, pollen, and mold allergens by the filter in residential HVAC systems. AllergyZone filters provide superior performance in three crucial areas, which we call the Filter Quality Triangle. Holding Capacity: AllergyZone filters hold up to 60% more dirt than other brands. Air Flow: AllergyZone filters allow for optimum airflow as they load with dirt. Efficiency: AllergyZone filters remove up to 95% of many airborne allergens. Each filter is constructed with premium grade components, including a 2-piece double wall frame for durability in the air stream. The unique, dual-layer electrostatic filtration media is composed of synthetic fibers that do not support microbial growth. The pleated media configuration is 500% more effective than ordinary fiberglass air filters. Each filter is individually sealed in plastic to insure cleanliness prior to installation.

They are slipping through the return vent so I had to tape across one end to make them stay. I've used several brands of filter in years past and never had this problem before. It's kind of hard to expect them to do their job correctly if they don't fit properly. ### ⭐⭐⭐⭐ The firs one came a bit smashed in shipping but work great. The second one came in perfect *by S***R on Reviewed in the United States on March 8, 2015* I have ordered several of these. The firs one came a bit smashed in shipping but work great. The second one came in perfect. The fit is perfect and it cleans the air as advertised. ### ⭐ Poor condition upon arrival and a bit smaller than other brands. *by A***S on Reviewed in the United States on September 6, 2014* The filter appears to be a little smaller and fit loose. I am not sure if it will affect operation. I did not have such problem with other brands. I had to use tape to secure it.Also, it arrived bent and banged up. --- ## 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.vu/products/36979745-allergyzone-az20301-air-filter-for-allergy-sufferers-20-x-30](https://www.desertcart.vu/products/36979745-allergyzone-az20301-air-filter-for-allergy-sufferers-20-x-30) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-03*
