Air Purifiers Too Expensive? Convert Your AC Into One Or Strap On A Filter To Your Fan

Do you want relief from the dangerous air pollution plaguing north India but find air purifiers too expensive? Here are a few alternatives that are almost as effective as a commercial one:

1. 3M™ Electrostatic Air Conditioner Filters
   These filters are the cheapest way to remove pollutants such as PM2.5 from your room. You can fix these filters on your air conditioner’s filters and run the AC on fan mode. 3M claims these filters remove around 83 per cent of air borne PM2.5 particles. This works on both window and split ACs. Installing this is very simple. Just open the top cover of your AC, which usually opens from both sides. Pull out the AC’s filters and clean them. Then stick the 3M filters on top of using the double sided tape given in it. Put the filters back in.
2. Attach HEPA filter to fan
   
   
   An air purifier is basically a filter and a fan. Fancy ones come with sensors to show the quality of air. If you just need clean air, strap on a HEPA filter on a table or stand fan, and you will get purified air that is as good as fancy air purifiers. You can buy HEPA filters from Amazon or here.
3. Buy a DIY air purifier
   
   You can simply buy a DIY air purifier that’s basically a fan and a HEPA filter. It costs just Rs 3,550. You can buy it from here.
