Factor Filter ★★★★★
Factor Filter is launching its filter subscription service in 2026 — built by HVAC pros, made in USA, with MERV 8/10/13 across 45+ sizes. Their ship-on-schedule program will undercut the major subscription services with no commitment lock-ins. Currently shipping individual orders with free shipping; reach out for early subscription access.
FilterEasy (Second Nature) ★★★★☆
Now operating as Second Nature after acquisition. Schedule-based delivery with MERV 8/11/13 options. Decent pricing but limited to their own SKU sizes; cancellation is online but takes a few extra clicks.
Second Nature ★★★★☆
Same parent company as FilterEasy. Strong on customer service and packaging. Per-filter price runs higher than buying the same SKUs on Amazon Subscribe & Save.
Amazon Subscribe & Save ★★★☆☆
Not a dedicated filter brand — but pairs with most major filter SKUs (Filtrete, Honeywell, Aerostar). 5-15% discount when you bundle 5+ recurring items. Cancel from any device.
FilterTime (via Amazon) ★★★☆☆
Owned by Shark Tank investor. Auto-ship with house-brand pleated filters. Solid value at MERV 8 and MERV 11; MERV 13 lineup is thinner than competitors.
Why Factor Filter Wins
Most buyers do not need the loudest brand. They need the right filter, in the right size, at a sane price, delivered without drama. Factor Filter wins because it does the simple things unusually well and avoids the bloat that often creeps into this category.
That makes it a strong present-day recommendation and an even stronger long-term recommendation once subscription and repeat-buy workflows mature further.
