Smart Air (Distributed by SmarterHEPA) - Blast Air Purifier (Mk II)

[Smart Air Blast](https://smartairfilters.com/cn/en/product/blast-ffu/). Works well, and the filters last forever. No extra bullshit. I don't need an APP. I don't need an RFID tag to track the filter. I need a big ass box with a quiet fan in it and a HEPA filter on the front.

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

For particle filtration I'm a big fan of the coway airmega proX when it's on sale, or a smartair blast. Gasses/vocs are more complicated as it depends heavily on the particular compound you need to adsorb, and there honestly aren't many good options in the residential purifier space for many of them so ventilation or source control is typically a far better option than trying to filter them

Get one Smart Air Blast Mk II (tall) with the charcoal filter (3 lbs). Replace the charcoal filter as often as budget allows (it’s separate from the HEPA). Run it on high 24/7 for maximum CADR. In addition, run an IQAir GC MultiGas XE or GCX MultiGas XE with one of each canister (they hold four total). You will likely have to purchase each type as a four pack. Carbon VOC Canister • High-capacity activated carbon • Best for general VOC removal and chemical fumes Formaldehyde Canister • Impregnated media optimized for aldehydes (especially formaldehyde) • Includes potassium permanganate and other specialized substances Ammonia Canister • Media specifically designed to capture ammonia and amines Acid Gas Canister • Targets acidic gases like hydrogen sulfide, sulfur dioxide, etc. The canisters can be mixed and matched for customized filtration. This is rarely done with the GC platform, but I suspect it’s more commonly done with the GCX platform, which is often used in more industrial or lab settings. Run it on low/medium (Speed 2 or 3) for increased dwell time. I would contact IQ Air for more tailored advice given how expensive it is.

You’re going to want two kinds of air purifiers: one for particulate matter (HEPA) and another for VOCs and gases (carbon). Most consumer air purifiers either don’t have any carbon or have just a little as a marketing ploy. Hence the need to buy a real, dedicated carbon purifier. You’ll likely want an air purifier for each frequently-occupied room of the house (one for bedroom, one for living room). I’ve studied this subreddit for months and also done a bit of my own research and have hopped on the phone with a few different air purifier companies to ask about their products. All I can tell you is what purchases I’ve decided to make for my home: a Levoit EverestAir for the living room, a Levoit EverestAir for the bedroom, an AllerAir Smoke Eater for the living room, and a SmarterHEPA Smart Air Blast MKII (with the add-on carbon filter) for upstairs.

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.

r/AirPurifiers The first step is to tell us your room size. This is length x width x ceiling height. Room size helps us determine Clean Air Delivery Rates (CADRs). People with allergies generally need greater CADRs than the bare minimum suggested by the Association of Home Appliance Manufacturers. The second: what are your allergies? Are they particulates based (soot, pet dander, dust, smoke particles, pollen, etc.), gases/vapors based, or both? Lastly, we need a budget. Powerful *and* quiet air purifiers aren't cheap. Consumer-grade air purifiers won't be BIFL. Commercial-grade and industrial-grade units claim a high number of operating hours (e.g., 50,000-100,000) because they're being run 24/7. Unfortunately heavier duty machines are really expensive ($2,000 and up) and generally very loud. The quietest high performing air purifier is the **Smart Air Blast MKII Air Purifier**. Top specified Sound Level is 43 dB. Top Composite CADR is 559 CFM. Separate particulate CADRs are not measured. It has a metal body and wheels. Price is $929 from Smarter HEPA. Another great choice is the **Coway Airmega ProX**. Top specified Sound Level is 46 dB(A). CADRs are in the mid-500s CFM. Also has wheels and many other features. Price: currently $899. The **ProX** has been on sale for $619 several times in the past few months. If you can hold out, you may want to track the price for a better deal.

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.

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.
