About Filters Fast
Filters Fast sells replacement water, air, refrigerator, humidifier, pool and spa filters, plus filtration systems and its own Filters Fast brand, from Charlotte, NC, since 2004.
Regular discounts are capped at $25 off, while Home Filter Club savings carry no cap, so a subscription can beat a code on a large order.
The company traces its start to 2003, when founder Ray Scardigno tried to buy a replacement refrigerator filter online and found very few small sites carrying them; he launched the store the following year. The catalog now runs to more than 10,000 filtration products for homeowners and businesses, mixing genuine brand-name OEM filters with tested Filters Fast compatible alternatives.
Certified filtration specialists on staff advise on MERV ratings, NSF certifications and appliance compatibility, and the site publishes buying guides and comparison tools. Shoppers can look up refrigerator filters by part number or air filters by exact dimensions. Beyond filters, the range extends to air purifiers, dehumidifiers, water softeners, thermostats, sump pumps and appliance parts.
