Can I stick a prefilter on the hepa filter (though I know it doesn't come with prefilter) . Will it work?

No, we don't provide any prefilter for QT3 HEPA. We'll also not recommend using prefilter as it would reduce the airflow and hence CADR significantly.

Can the hepa filter get fungus or damaged if I use very occasionally ? (only during traveling,I.e.2-4 times a year)

That's a good question. The purpose of a HEPA filter is to capture tiny particles such as PM2.5, bacteria, dust, etc that are present in the air. If the HEPA filter is not used for a long time and is kept under moist conditions, then it MAY lead to the accumulation of bacteria. In that case, you need to put the HEPA filter in the sun and run it outdoors. Another solution if you're not using the HEPA regularly, you can keep the HEPA filter inside a plastic bad to avoid moisture and bacteria attacks.

Where to get the replacement filter when needed

Thanks for asking the question. Kindly provide us with your Amazon order number and we'll help you with the QT3 replacement HEPA filter

Kya 14*14 feet room ke liye compatible hai?

This is a personal purifier. Although it’s not designed to clean a whole room, the QT3 portable purifier reduced PM2.5 by an average of 76% in a 13m2 (130 sq ft) room in overnight tests.

worth to buy- stylish purifier

Super happy with this QT3 air purifier. Aesthetically pleasing and functional at an affordable price. It’s portable, but not heavy to move around. I carry it to my workplace, café and also inside the car.Tested the battery and it gives me a battery life of more than 3 hours. The good thing about this air purifier is that I can charge it with a power bank.Love the design. It also comes with a separate compartment to store cables. Must have a product for Delhi’s air pollution.

Perfect stylish and ultra useful

I got this air purifier few days back and it is really good looking and yet powerfull. I have been using smart air filters product for quite some years and i totally trust their products. They are more of diy company. I have used their diy -2 and still use it. This company has in depth study and knowledge about air purifiers and pollution and their effects.I bought the battery version as its best suited for a portable purifier.I also bought it so tht i can use it as a table faan during summers or monsoon.It is working perfectly. I get good backup on battery. Also good thing is it works even while charging.Its very sturdy body and has a simple mechnism.U get a usb cable free.I wish they keep replacement filter costs to minimum.
