Clean Air is not a Luxury

Our Original DIY Air Purifier is a simple and low cost yet effective purifier that eliminates PM2.5 and PM10 particles.

Our tests show that the Original DIY can remove up to 82% of PM2.5 particles from a 150sqft room, all for the under Rs.4000

How does it compare to expensive purifiers?

We tested this simple DIY purifier against some of the biggest brands on the market, and found that the simple DIY performed almost just as well as purifiers costing over 20 times as much!

 

Does it really clean the air?

Tom the founder of Smart Air and a professor at the University of Chicago tested this using a laser particle counter. What he found was that even low cost filters and fans can provide clean air. Watch this video to see the test he did.

How often should I change my filter?

We recommend replacing your filter after 90 days of use at 8 hours a day at the latest. That’s maximum 720 hours in total. We ship replacement HEPAs starting at Rs.1300 from our store.

Why 90 days? Smart Air co-founder Gus tested a single HEPA on his Original DIY for 200 days in Beijing to see how long it would last in real Beijing air. After 100 days of use at 8 hours a day, effectiveness dropped 4%. After 200 days of testing, Gus’s dirty filter was only removing half the particles in the room.

India’s air is on average more polluted than Beijing’s air, so in India we recommend replacing the filters sooner, at 90 days or 720 hours.

We know that buying new HEPA filters is a significant recurring cost, so we do our best to keep prices low.

    It is exactly as advertised. Cant say much about effectiveness as dont have air quality checker, but the filter started turning black within 2 days. Thats enough to say it works.

    A drummed-down air purifier that does just what it needs to do – purify air. The one year kit is the best package, in my opinion. Best to go for 1 one year kit and then additional DYI Air Purifiers if required.

    Works well.. noticable difference in the air quaity as am able to breathe better with substantial difference in stable sleep ..am ordering two other for the other rooms

    Two suggestions :

    1) the velcro strips provided should be two for holding the filter tight to the fan and also prevent the filter from falling/slipping off
    2) add some weight to the base of the fan so that the unit is more stable, If i put the fan at an angle the unit becomes unstable

    Also have a Question : Is the pre filter washable ?

    • SmartAir (verified owner)

      Hi Gaurav,
      The pre-filters are not washable.

    As of now looks good…Can feel the slight difference in the air quality.
    Not sure how much effective it is but some effect I can notice for sure.

    This is a very cost effective and simple setup. Filter replacement ( HEPA ) which needs to be done regularly in our current poor air conditions is also pretty cheap.
    The main drawback that i experience with this setup as against other brands is that it tries to push air and most of the air is reflected back. So the amount of air passing through the filter is much less. Traditional air purifiers use a suction to pull air rather than push air and cleans a much larger volume of air compared to this model.
    I hope that with the improved model that is being introduced – Canon, this problem will be much reduced.

    I am in Navi Mumbai and area is not that much polluted. Since I suspected some dust allergy problems and the result in EṣR count,I bought the Original DIY Air purifier 2 months and it is working very well. Dust I have seen earlier gets accumulated.HEPA is not turning black so far. Still I feel it is worth for the cost that I bought (Less than Rs.4000 – at my doors). I do not cough if the fan is stitched on now.

    I strongly suggest to all those who have respiratory problems, even if they live reasonably non-polluted area.

    This product is very good under the prescribed conditions. The evidence of its effectiveness is clear when you replace the used filter. Every particulate trapped by this used filter is likely one less particulate in your lungs. And trust me, it literally turns from white to black at the end of 2 months.

    I am using the original DIY and it works, that too at a pocket friendly price. Only one problem though with ALL air filters- one has to keep the doors and windows completely shut for extended periods. As a result the co2 levels can shoot up

    • Jay Kannaiyan

      Hi Anand, thanks for the feedback and you’re right, the problem with room-based air purifiers is that the closed space leads to an increase in CO2. Now, CO2 is not going to be harmful until it reaches really high levels so it’s sort of a trade off of which pollutant is more harmful to us. Particulate matter is harmful even at low levels. One way to alleviate a CO2 build-up is to simply open the windows for a short period of time every day – late afternoon is usually the best time of day for particulate matter.

    I have a question here, can i separability buy HEPA filters?

    • Paddy Robertson (verified owner)

      Hi Joseph, if you have your own flat-faced fan, sure you can buy a HEPA filter and strap it to your own fan! We have HEPA filters on our HEPA filters page. If you’re going to use your own fan, things to make sure are:

      1. The front of the fan is flat, that way you can ensure you get a good seal round the HEPA filter and no air leaks round the side
      2. The fan you’re using is strong enough to blow air through the HEPA filter. This one’s more difficult to test. We’ve tested the fans we use so know the size of the room they’re suitable for, if you can find fans comparable to the Original 2.0 DIY or the Cannon then you should be good to go!
