98% PM2.5 AC Filter Silver Ion

Physical specs: 5.2 × 21 cm (2.05 × 8.27 in), lightweight sponge build; functional attributes: 98% PM2.5 filtration efficiency, silver ion antimicrobial infusion, heat-tolerant composition, snap-on mounting system; package contents: 2 filter pads. Engineered specifically for retrofitting into existing air conditioning vent systems, these filters intercept airborne pollutants *before* they re-enter occupied spaces. The silver ion additive remains effective throughout the full service life — not just at initial installation — and works synergistically with the sponge’s pore density to trap and neutralise contaminants. Each unit undergoes dimensional consistency checks to ensure uniform fit across common UK vent profiles. Recommended for environments where air purity directly impacts wellbeing: homes with infants or pets, WFH setups with limited window ventilation, and older buildings with less advanced central air handling. Delivers noticeable improvement in perceived air freshness within days of installation — especially during pollen season or post-renovation dust periods.
