Smart Air (Distributed by SmarterHEPA) - Air Blast Mini - MKII

I wouldn't say a purifier isn't doing anything if it's on low speed. I understand in most cases you are correct ..or at least for most casuals....but for my Smart air blast mini, I can run it on speed 1 24/7 in my living area since I don't need 6ACH for pollen. All I'm saying is, it depends on the use case.

I have a smart air blast mini in my living room and an iqair in my bedroom, but on your budget I would replace the iqair with a coway or even do 2 smart blast minis if you have the space

Just got the Smart Air mini and am very happy with it https://www.smarterhepa.com/products/smart-air-blast-mini. With your budget you could even go with the Smart Air blast.

I second the Smart Blast Mini! I have one and it works great. It has a very high CADR (clean air delivery rate) so in a small place with just one living room and 2 bedrooms, all that may be required is one. Unfortunately they raised the price recently due to tariffs, so it's over $700 now, and OP couldn't afford two. I'd go with a Smart Blast Mini for the LR and an SA600 (same brand) for the bedroom. OP, see this [link](https://smartairfilters.com/en/shop/?=header) for the purifiers.

Yes, air purifiers are worth it. I have a portable air quality monitor that measures PM2.5 and VOCs and when I'm blasting my air purifiers I watch the PM2.5 and VOC counts go down significantly. You need to make your purchases wisely. Pay attention to the CADR (clean air delivery rate, usually measured in cubic feet per minute (cfm) and the square footage (in cubic feet) of the area you're trying to clean. You'll want to aim for at least 6-8 air changes per hour, but even 3-4 is better than nothing. To calculate the number of air changes per hour (ACH), ACH = (CADR x 60) / Room Volume For example, I have a [Smart Blast Mini](https://www.smarterhepa.com/products/smart-air-blast-mini) with hepa + carbon filters which has a very high CADR of 820 cfm, giving me a superlative bang for my buck. I have a sunroom and dining room off the living room so I can use the Smart Blast for that area. Let's say you're looking to purify the air in a 20 x 20 LR plus an adjacent 12 x 13 DR and 11 x 9 sunroom with 8' ceilings. The total square footage = 8 x (20 x 20 + 12 x 13 + 11 x 9) = 5,240 cubic feet (cf). ACH = 820 cf x 60 min/hr /5240 cf = 9.4 ACH which is very good.

I recommend [this one](https://www.amazon.com/Qingping-Temperature-Humidity-Upgraded-Function/dp/B0CZ85RT6C/ref=sr_1_1?crid=3F5A48JDTFDTE&dib=eyJ2IjoiMSJ9.5KcncewEyArPaKRv_N-DHw.grH0G1BnrdOsgQP1GOPZiDWfuT9CfzC3PGuoyV-6p3Y&dib_tag=se&keywords=smart%2Bair%2Bqingpong%2Bpro&qid=1758783695&sprefix=smart%2Bair%2Bqingppo%2Bpro%2Caps%2C122&sr=8-1&th=1). We have it and it works very well. Whenever we use our (unfortunately gas) stove or oven, the total VOC count goes in the red. We're planning to buy an induction range. In the meantime, our [Smart Blast Mini air purifer ](https://www.smarterhepa.com/products/smart-air-blast-mini?variant=41889323385016)with HEPA and VOC filter works great for getting VOCs and PM2.5 down quickly. It's very powerful. We also utilize our range hood and open windows when weather allows.

Yes, like a Smart Air Mini! [Either way, here is a great list of reviewed purifiers that work against VOCs (farts, among other things)](https://housefresh.com/air-purifier-for-vocs/)

I have 3 cats in my apartment. I'm running the air purifier 24/7 so I went with the Smart Air's Blast (cost around USD630 or something). Makes a huge difference.

Smartair Blasted MKII is very quiet with very high CADR due to the size of the filter.

Smart Air (SmarterHEPA in the US) is our main filters with an AustinAir in the bedroom. AustinAir is one of the only with a large amount of carbon or carbon fabric in them for VOCs and odors.
