What AirFilters does

AirFilters.com is a direct-to-consumer e-commerce platform that sells residential and light-commercial HVAC air filters, operating exclusively through its own online storefront at airfilters.com. The company, headquartered at 3440 Industrial Drive in Durham, North Carolina, offers more than 3,000 standard filter sizes plus custom-size fabrication across thickness profiles of 1", 2", 4", and 5"+ and MERV ratings spanning 6 through 13, including proprietary Accumulair house-brand lines (Diamond APR 1950, Platinum APR 1550, Gold APR 650, Carbon) and brand-specific replacements for Carrier, Lennox, Honeywell, Trane, Aprilaire, Trion Air Bear, and 30+ additional HVAC manufacturers.

The underlying technology centers on physical filtration media, primarily electrostatically charged synthetic pleated media with activated-carbon variants for odor reduction, and the products are manufactured in the USA. Differentiators include configurability (custom sizes), MERV-graded efficiency (MERV 13 captures 80-90% of dust spot efficiency and removes bacteria and some viruses), and a content-led discovery experience organized by size, brand, and MERV tier rather than algorithmic recommendation. The company carries a BBB accreditation badge and offers a 60-day return policy on standard filters.

Commercially, AirFilters.com runs a two-track revenue model: one-time catalog purchases (4-packs, 6-packs, 3-packs priced from roughly $40 to $318 depending on size and MERV tier) and a Subscribe & Save recurring delivery program offering 10% off automatic reorders. Shipping is nationwide across the 48 contiguous states via FedEx/UPS with free shipping at $99+, and fulfillment is supported from North Carolina with a returns/warehouse site in Wellford, South Carolina. The company is a wholly-owned subsidiary of Freudenberg Filtration Technologies following the 2021 acquisition from PPA Industries, with RPS Products integrated into the platform that same year; primary customer segments are residential homeowners seeking convenience, allergy/asthma sufferers, pet owners, and consumers needing non-standard sizes.

Products and services

• Accumulair Filters (House Brand) Proprietary Accumulair line of MERV-rated replacement air filters sold under the AirFilters.com house brand, spanning Diamond APR 1950 (MERV 13 equivalent), Platinum APR 1550, Gold APR 650, and Carbon MERV 10 filters. The line uses electrostatically charged synthetic media to capture pollen, dust, pet dander, smoke, and odors, and is sold in standard sizes and multi-packs for residential HVAC use.
• Trion Air Bear Replacement Filters Aftermarket replacement filters designed specifically for Trion Air Bear air filtration systems, available in MERV 8 and MERV 13 ratings with deep-pleat construction. Targeted at owners of Trion Air Bear whole-house air cleaners seeking compatible replacement media.
• Carbon / Odor Air Filters Activated-carbon-impregnated MERV 10 air filters designed to reduce odors, gaseous vapors, and chemicals while still capturing standard airborne particulates. The carbon is built into the electrostatically charged synthetic media for combined odor and particle performance.
• Custom-Size Air Filters Bespoke air filters built to exact customer-specified dimensions for non-standard HVAC systems where off-the-shelf sizes do not fit. Filters are made to order, carry a longer lead time (approximately 10 business days to ship), and are non-returnable.
• Whole-House Air Filters Furnace and air-conditioner filters designed to supply conditioned, filtered air throughout an entire residential or small-commercial structure, available in standard and larger 4" and 5"+ thicknesses within the AirFilters.com catalog.
• Washable and Metal Mesh Air Filters Reusable air filters that can be cleaned and reused rather than replaced, including metal mesh options for extended service life. Targeted at residential customers seeking a longer-lasting, lower-waste alternative to disposable pleated filters.
• HVAC Brand-Specific Replacement Filters Aftermarket replacement filters for specific HVAC brands (Carrier, Lennox, Honeywell, Trane, Aprilaire, Bryant, Goodman, and 30+ additional manufacturers) that fit proprietary OEM filter slots and whole-house systems. Offered as a more cost-effective alternative to OEM originals while maintaining fit and filtration performance.

• Amazon (HVAC Filters Category): Amazon's HVAC filter category aggregates thousands of SKUs, including Filtrete, Honeywell, private labels, and direct sellers, with Prime shipping and Subscribe & Save. It is the dominant online competitor to AirFilters.com, offering comparable selection with faster fulfillment and lower friction for many buyers.
• Home Depot (HVAC Filter Department): Home Depot operates the largest offline and online retail channel for residential HVAC filters, carrying Filtrete, Honeywell, and private-label brands.
