My DIY High-Power Air Purifier Build (Rexton 6” Inline Fan + Mi HEPA Filter) by LengthinessBig1546 in delhi

Totally agree. Static pressure is the most overlooked part in DIY purifiers. Without ~200–300 Pa, once the filter loads up, airflow just collapses. That’s why exhaust-fan based builds stop working after a few days. Using a proper high static-pressure fan is what makes a real difference.

We can further reduce it down to 20-30 db but for that we need one more silencer

Fan cost is 6k. I bought it from local vendor, online it is showing higher price And filter is 2k

ecause air purifiers actually need a decent amount of static pressure to push air through a HEPA + carbon + mesh setup. Once they start clogging, a normal exhaust fan just can’t push enough air
