## Questions & Answers

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

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

**Q: Where to get the replacement filter when needed**
A: Thanks for asking the question. Kindly provide us with your Amazon order number and we'll help you with the QT3 replacement HEPA filter

**Q: Kya 14*14 feet room ke liye compatible hai?**
A: 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.
