Islamabad and Rawalpindi residents now live with air pollution levels that regularly exceed WHO safe limits. We obsess over outdoor air quality but forget that, on average, we spend 90% of our time indoors where particulate concentrations can actually be 2–5x higher than outside if the home isn't designed correctly.
What your standard AC does and doesn't do
A regular split AC recirculates and cools the same indoor air. Its filter catches large dust particles but does nothing against PM2.5, smoke, VOCs, or allergens.
Upgrade #1: HEPA-grade pre-filters
Many modern inverter ACs (Mitsubishi, Daikin, Gree top models) accept add-on HEPA filters that capture 99.97% of particles down to 0.3 microns. AF Tech Fix retrofits these on existing units.
Upgrade #2: Fresh-air ventilation
Adding a small ERV (energy recovery ventilator) brings in filtered outdoor air while exhausting stale indoor air, with up to 80% heat recovery. Critical for sealed modern apartments.
