Filtrete™ Healthy Living Deep Filter (MPR 1550)

Filtrete deep-bed pleated air filter with MPR 1550 (≈MERV 12). Designed for whole-house media cabinets, with depths of 2", 4", 5", and 6". Greater pleat surface area means longer life and better fine-particle capture than 1" filters. Made by 3M. What MPR 1550 actually means. MPR 1550 in 4–6″ deep-bed format is roughly equivalent to MERV 12. The deep pleat geometry yields significantly more media surface area than 1″ filters, which lengthens replacement intervals and reduces airflow restriction at the same efficiency rating. Who it's for. Homes and small commercial spaces with media cabinets or 4–6" filter housings; high-efficiency, low-maintenance air quality. When to replace. Every 6–12 months depending on depth, use, and indoor conditions. Inspect monthly — if light no longer passes through the pleats, it's time to change. Sold in cases. Most sizes ship in cases of 4. The 16x20x4, 16x25x5, 20x25x5, and 20x25x6 sizes ship in cases of 2. The case quantity is shown on each variant and enforced at checkout — order quantity must be a multiple of the case size.
