So my parents need an Air Purifier for home use. Which ones can I go for?

What I'm looking for:
  1. Average or lower filter replacement cost.
  2. Ability to work long hours.
  3. Good after sales (I've heard bad things about Mi)
  4. 'Smart' features not necessary.
  5. Should filter all bad stuff like PM 2.5 etc.

Budget is around 10K max. Suggestions.?

Also you can post your reviews of your air purifier here, we all like to read them.

Thanks!

I have a Mi unit and it is struggling these days. Has been running 24x7 and the 2.5 value is still 600. Just replaced the filter. Now waiting to see if that helps.

For around Rs. 10,000, I would recommend Mi. Better products cost much higher. Sharp, Blue Star are the brands that are supposed to be the best in the market.

The doc file list models that have washable filters. But they cost more than 20K. If I knew things would go this bad in NCR... I would have gotten one of those models.

Check out the myhealthbeijing site. Get the Mi air 2, it has a sensor. Don't think it's really accurate, But you can check. Another cheaper option is Smart Air Original or Smart Air Cannon, which you can also buy from their office.

Air purifier should get the levels to near zero. I think for it to work, you have to have air coming in less than what purifier can filter per hour, as purifier can filter 99%. Otherwise pollution inside will be to some extent. My MI air 2 is getting it to 60 - 150, but I have a little opening in the window. I will get it fixed and seal some gaps in doors and windows (leaving enough for oxygen) and see what happens.

so purifier with washable filters is one time investment? buy it once and when filter is dirty, just wash them?

The only Air Purifier in India which has NO RECURRING COST OF BUYING FILTERS every 4-6 months like HEPA FILTERS which all the others brands are selling. LASKO Air Purifiers have most advanced filtration systems which effectively captures air borne particle, even the more harmful atomic size particles that HEPA filters can leave behind, even if you switch off the machine the dead PARTICLES ARE NOT REGENERATED which is not the case with HEPA filters. Have permanent stainless steels washables filters with a life span for more than 15 years, patented Zero3 technology, energy efficient.
