Review: The Best Air Purifier!! - The best air purifier I purchased. I bought this item because I live in an ADU and it is attached to the main house and I have to share with the main house ventilation and one night I had to smell weed coming from the main house. So I looked up what is the best purifier on desertcart? And it says PuroAir 130i and so I bought it. Reasonable price. Once I turned it on and use it, it works beautifully. The fan speed is great, when it’s on low noise level, it’s very quiet, it doesn’t wake me up when I’m trying to sleep, and the brightness is just right. I use the app to control the air purifier so I don’t have to worry about it. It’s very easy to set up. I’m very happy with this product. I would 100% recommend buying this item.
Review: Clean Air!! - Great purifier, compact, quiet, and does a great job for the room. Like it has sleep mode and seems to be built well. Very pleased with purchase.

## Questions & Answers

**Q: Is the filter washable and if not, where do i get more?**
A: Washing filters has shown to reduce effectiveness by 40-60%, I highly recommend just replacing filters if you want the device to work at a 100% level.

**Q: Does this  purifier produce ozone?**
A: No this unit does not produce ozone per its California Air Resources Board certification. Please type "Puro Air" in the below link for proof that this unit does not emit any ozone per the California Air Resources Board certification the unit has received. 

"Air cleaners that are listed as "Electronic" may be capable of generating small amounts of ozone, but have been tested and found to produce an ozone emission concentration less than 0.050 parts per million. This category includes ionizers, electrostatic precipitators, PCOs, hydroxyl generators, devices with UV light components, and other electronic air cleaning technologies."

**Q: Is there a filter included in the purchase**
A: Yes, there is a yellow tag on top of unit that reminds you to remove plastic wrap from filter before use.

**Q: How long do the filters generally last?**
A: We have had our Purifier for about a month and the filter still appears pretty clean. We have 2 dogs and a cat, I will probably replace our filter around the 3-4 month point. In general I would think most filters would last 3-6 months depending on pets or location. A dry dusty area or musty area would make a difference in what kind of particles will go through your filter. I would suggest checking monthly like you do a home furnace filter.

Great purifier, compact, quiet, and does a great job for the room. Like it has sleep mode and seems to be built well. Very pleased with purchase.

### ⭐⭐⭐⭐⭐ Quiet and Effective
*by S***S on July 18, 2026*

The filter seems very good: quiet and capable. It is better than the Whirlpool filters, the last Whirlpool failed after a couple of years. So, I am hopeful that the PuroAir will serve for at least four or five years ... maybe more. These types of filters have been essential when we experience severe smoke from wildfires. The filters seem pricey but I think that they may be more effective. I noted that the carbon filter part should be brushed off ever month even though the HEPA filter lasts 2 to 3 months.
