HEPA Carbon 3Layer Replacement Filter

Designed for widespread compatibility across UK-market air purifiers, this replacement filter set occupies standard cavity dimensions and weighs about 0.8 kg. Its tripartite architecture includes: a textured synthetic prefilter that collects lint, pet hair, and textile dust before they reach deeper layers; a dense activated carbon zone targeting gaseous emissions from frying, baking, smoking, and off-gassing furniture; and a medical-grade HEPA layer rated to trap 99.97% of particles at 0.3 microns—including grass pollen, mould hyphae, and diesel particulate matter. All materials adhere to EN 1822 (HEPA), EN 13725 (odour), and EN 779 (general filtration) benchmarks. The rigid frame incorporates reinforced corners and micro-perforated airflow guides to ensure even distribution across the entire media surface. Fits seamlessly into OEM housings—no cutting, folding, or force required. Replacement typically takes less than 2 minutes and does not affect warranty status of the host appliance when installed per manufacturer instructions. Recommended replacement frequency is every 6 months in average-use homes and every 4 months in homes with elevated airborne load (e.g., near construction sites or with multiple pets). Particularly valuable for households managing hay fever, asthma triggers, or post-renovation air quality concerns. Also supports improved sleep quality by reducing nocturnal airborne irritants and maintaining stable humidity-neutral airflow throughout the night.
