Blast Air Purifier (Mk II)

Smart air blast has the best sound of all my purifiers by far

Search high CADR purifiers. My recommendation is if you are ok spending the money on an iqair unit, to look at other options since you have multiple rooms. What I see right now is the levoit EverestAir on clearance for $299 from Bestbuy. It is an excellent choice with a high 350 CFM CADR. (I just got 2 more at this price) a “comparable” unit is the levoit core 600s-p(sale price 299 410cfm CADR) if the Everest is not on clearance. I would buy the core at the sale price. Owning both the Everest is better in my opinion. As others have stated multiple units will provide more benefit than one large unit. However again if you are spending that money and like iqair please consider the Atem-X as it has a very high CADR. Another option is the SmartAir blast MKII. This is a beast of a unit that targets commercial applications but is generally at the same price point as the larger IQAir units but proving a much higher CADR. I have one sitting in my 600sqft Great room.

FWIW you need to measure individual rooms and target the best or most frequent areas. The size of the house is somewhat irrelevant as these air purifiers work with smaller spaces. Additionally air purifiers are marketed very deceptively if you are not familiar with CADR or AC metrics. Some manufactures list square footage “up-to” a certain square footage. This is typically for 1 Air change rate an hour. For a decent filter in a room (that is used) you need at least 3 air changes for hour but the recommendation is 4.8 so I use 5 for my measurements. Will smaller air purifiers work? To some degree yes but they will take a very long time to clear out existing particulate matter from the air. So how does CADR fit in? It’s the actual measured rate at which clean air can be delivered by the unit. By knowing the CFM (cubic feet per minute) of the CADR (clean air delivery rate) you can size accordingly. budget constraints can definitely put pressure on your decision making but I would try to go with the larger most cost affordable option to get a better option. My suggestion would be the levoit Everest. Most places have it for $500 but for some reason BBY has them on clearance right now for $299. This single unit my provider more filtered air than the individual smaller units combined. I just added 2 more. Remember over sizing is ok but undersizing will take much longer to clear out existing particulate matter not accounting for new load. Additionally the Everest has wheels and can be easily moved. It is advertised as up to 2656 sq ft. This is for 1 air change. However we can see to hit the target 4.8 air changes to filter the air means this should really be used in a room no larger than 550 sq ft. If that doesn’t work in the budget focus on the smaller rooms for sure and size the air purifier accordingly. Otherwise you may feel like you wasted money and that air purifiers are not working. For what it’s worth I have shark never change (not great for large rooms but nice for bedrooms) the levoit plasma core 600 for our living room, the levoit Everest is in 4 bedrooms (price per performance while on clearance is hard to beat outside of DIY), a smart air blast mkII, and a 20x20 CR Cube with an 16” drum fan (garage) If you’re crafty a DIY Corsi Rosenthal cube can out perform every one of these for under $200 but the aesthetics are not very appeasing. (Hence why mine is in the garage) TLDR - sizing is important and advertising is not straightforward in regards to actual coverage.

Exactly as u stated. All depends on your goal. And yeah I wish I had the Full size smart air blast instead of the mini but they were out of stock. It really doesn't saturate with smells either...it's great

Large Smart Air Blast with a yoorair clean freak after the Hepa. This will cut your CADR/CFM in half. Cost will also go up as well and the carbon filter pad only really last a month. You're still at 200 at the lowest setting and 400 at the highest fan speed. I like yoorair because the thing they wrap around the carbon filter pad doesn't allow carbon dust to leak out but it's like also super dense with a merv 6 rating, the filter pad is like merv 4 if their specs are to be trusted. Or you can just use their carbon filter and change it every 2-3 months.

An Iq air healthpro. I've also had a smart air blast mk 2 and the levoit 300s 400s and 600s.

700 square foot apartment, and I love mine. It’s my third one. I’ve tried others and they don’t even come close to this for my particular issues. I’ll never buy another brand again. (I lost first 2 Health Pro+’s to two consecutive moldy rentals. Bad luck, for sure. They still worked great, but I didn’t want to chance bringing them with me.) Edit: I have had a smaller Levoit, and the SmartAir Blast which was industrial sized. Neither came close to the IQ Air for me. I was so bummed I got the Blast instead of the IQ Air. (Lost that to one of the moldy rentals too.) The quality of clean air from the IQ Air makes the ugliness and footprint it takes up worth it to me. I wish it were pretty but it’s a total eyesore that I will go back to again and again.

I have MCS, MCAS, & asthma, among other things, and love my IQ Airs. I do know some folks have an issue, but I haven't nor has my friend who also has such extreme MCS that she breaks into blisters from simple exposures. I own two of them, now giving them away because they've been in a home that ended up with pretty severe mold issues in the attic and I want to start new because it's impacted me so much. The quality of the air to me just doesn't compare between the IQ Air and my Levoit, my CR Box, or my SmartAir Blast (I have the industrial sized). I would have thought the SmartAir Blast would have had similar outcomes as the IQ Air but, to me, IQ Air all the way. Huge difference. There is a very subtle sweet smell that is associated with one of the products they use (in their filters, I think?). It bothers some. I am extremely sensitive, in general, and this doesn't bother me. In fact, I like it because I associate it with crisp, clean air. I wonder if there might be a store you can go check one out? Or, perhaps you can rent one for a test drive? I've rented an air purifier before while traveling for a hotel that had recently been remodeled and was causing me significant issue. It may sound like I'm loaded having all of these expensive machines. I wish. It would make things much easier. I'm just desperate for clean air and so extremely sensitive that it's caused major life disruption and I've needed to spend money even when I don't have it. (No experience with the AllerAir.)

Yes. It is the best PM2.5 filter you will find. The full size is a bit quieter and more effective, but large. If you want the best of the best, I would suggest going that route. Yes, I would highly suggest you make sure your HVAC system has appropriate filters on it for your system if possible, to keep the HVAC system clean and reduce mold formation. I would invest in a high end steam cleaner, especially for the floors, as well as a HEPA vacuum such as a Miele or Sebo. I would use the robovacs for vacuuming and mopping maintenance on a daily schedule as well, and try and have minimal carpeting/rugs in the home.
