We bought these 2 filters for a little bit more than what we were paying for 1 from our heating and cooling company. Bought name brand so they do fit perfectly. Have been using this brand since we got our new system 5 years ago. Great quality to help keep our heat pump working well. My husband's allergies are kept clear by using these filters. Air seems fresher and our system seems to run more smoothly. Review: #1 Choice - These heater filters do the trick! They fit my heater intake well. They don’t rattle making the seal great. They seem to last longer and remove dust perfectly. I am pleased with the price. I’ve purchased this item for over 10 year, so you see they are my #1 choice. ## Features - MERV 11 - High-efficiency alternative to one-inch filters - Fits the X6660 HCC20-28 Air Cleaner - Nominal Filter Dimensions: 20x25x5 Actual Dimensions: 19-3/4" x 24-3/4" x 4-3/8" - Genuine Lennox OEM Furnace Filter ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008D7URTG | | Air Filter Construction | Pleated | | Best Sellers Rank | #17,405 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #166 in Furnace Filters | | Brand | Lennox | | Brand Name | Lennox | | Common Applications | Residential | | Compatible Devices | Air Cleaner | | Compatible Hvac Systems | residential | | Customer Reviews | 4.8 out of 5 stars 5,080 Reviews | | Filter Mounting Type | Slide In | | Filter Shape | Rectangular | | Item Dimensions L x W x Thickness | 25"L x 20"W x 5"Th | | Item Weight | 4.54 g | | MERV Rating | 11 | | Manufacturer | Lennox | | Manufacturer Part Number | X6673 | | Material | Fiberglass | | Material Type | Fiberglass | | Model Number | X6673 | | Number of Items | 1 | | Number of Packs | 2 | | Product Dimensions | 25"L x 20"W x 5"Th | | Product Grade | new | | UPC | 193802156652 | | Unit Count | 2 Count | ## Images ![X6673 Healthy Climate HCF20-11 MERV 11 Filter Media (2 Pack) - Image 1](https://m.media-amazon.com/images/I/714l+4j0MXL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ More smoothly running system with new filter. *by D***Y on January 30, 2026* Why are filters so expensive?

The box was damaged as well as the filters and we had to return it. They did send another one which came damaged as well just not as bad and we were able to use the filters. Much better packaging and handling would definitely help! --- ## 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.us/products/28640448-x6673-healthy-climate-hcf20-11-merv-11-filter-media-2](https://www.desertcart.us/products/28640448-x6673-healthy-climate-hcf20-11-merv-11-filter-media-2) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-24*
