BreatheSmart 75i

Today I want to quickly go over a few KEY things you should consider when choosing an air purifier. Here's a quick list of the best air purifiers for every purposes at every budget for those who don't want to read a long guide below. # Best Air Purifiers To Buy Rigth Now Best overall air purifiers for home use are [IQAir HealthPro Plus Air Purifier](https://airpurifierworld.com/best-air-purifier-for-home/#IQAir_HealthPro_Plus_Air_Purifier) \- [Coway Airmega 400S](https://airpurifierworld.com/best-air-purifier-for-home/#Coway_Airmega_400S) Best air purifiers for pets hair and dander:  [Levoit EverestAir](https://airpurifierworld.com/best-air-purifier-for-pets/#Levoit_EverestAir) and [Alen BreatheSmart 75i](https://airpurifierworld.com/best-air-purifier-for-pets/#Alen_BreatheSmart_75i_Air_Purifier) Most recommended air purifiers for dust: [Blueair Blue Pure 211+](https://airpurifierworld.com/best-air-purifiers-to-get-rid-of-dust/#Blueair_Blue_Pure_211) \- [Levoit EverestAir](https://airpurifierworld.com/best-air-purifiers-to-get-rid-of-dust/#Levoit_EverestAir) \- [GermGuardian AirSafe AC3000](https://airpurifierworld.com/best-air-purifiers-to-get-rid-of-dust/#GermGuardian_AirSafe_AC3000) For musty smell and molds: [Winix 5500-2 Air Cleaner](https://airpurifierworld.com/best-air-purifiers-for-molds/#Winix_5500-2_Air_Cleaner) \- [Dyson Purifier Humidifier+Cool Formaldehyde](https://airpurifierworld.com/best-air-purifiers-for-molds/#Dyson_Purifier_HumidifierCool_Formaldehyde) \-[Honeywell HPA300](https://airpurifierworld.com/best-air-purifiers-for-molds/#Honeywell_HPA300) # Shopping Guide There are two broad types of pollutants you can filter. There are particulates (for example: pollen, mold, dust, animal dander, soot, smoke particles) and gases (for example: vapors, fumes, odors, VOCs). \-If you want to filter particulates, the most important metrics are the Clean Air Delivery Rates (CADRs). CADR shows how quickly and efficiently an air purifier can remove particles from the air. A higher CADR means faster and better performance, especially in larger rooms. Coverage in square feet or square meters is not as important. Follow the [AHAM 2/3 rule](https://ahamverifide.org/ahams-air-filtration-standards/) for bare minimum CADRs. Smoke CADR should equal a room's area for wildfire smoke treatment. Both assume an 8 ft. ceiling height. Loads of brands lead with misleading coverage ratings in square feet or square meters. The Levoit EverestAir says it processes 2,635 sq. ft. of air once per hour. But 1 Air Change per Hour (ACH) is far too low; the minimum number of ACH should be 4.8-5 for normal circumstances. \-If you have a significant issue with gases, vapors, or odors which can't be mitigated with source control or ventilation, you need a second purifier just for these pollutants. That's because most particulates-focused air purifiers have very little sorbent media. Sorbent media is activated carbon, activated alumina, or synthetic zeolites. ***Also, cost of maintenance shouldnt be missed. There are two cost components in owning an air purifier. The upright fee and the cost of maintenance. Filters are replaceable and you need to buy a new one when it becomes saturated, otherwise, it will not be efficient in cleaning anymore. Some filters are cheaper, but they often need to be replaced more often than more expensive filters. So you have to consider this continuing cost if you decide to buy air filters.***

Alen, Coway, Winix are all excellent brands. Alen is the only BIFL option as they have a lifetime warranty for as long as you buy genuine Alen filters. It’s worth noting that a purifier isn’t going to do much for \*\*visible\*\* dust. You’ll likely need to upgrade your vacuum to something corded and bagged (check [r/vacuumcleaners](r/vacuumcleaners))

Both Shark and Dyson are junk tbh. No purifier will help with hair in any meaningful capacity. You’ll want to upgrade your vacuum to something corded and bagged if that’s the case. r/vacuumcleaners How big is your space? I’m a big fan of Alen, they are excellent quality and one of the only (if not the only) purifier that has a lifetime warranty for as long as you buy genuine Alen filters. Coway and Winix are also well loved on this sub. Which specific model depends on your space.

You may want to investigate a whole house air filtration system if you indeed have the budget. Otherwise your options are basically something like AirPura, it filters both air and uses large amounts of carbon to get rid of smells.. [https://www.airpura.com/](https://www.airpura.com/) An alternative would be something like the Oransi, this is just a carbon filteration, so smells only.. [https://oransi.com/collections/truecarbon-air-purifiers](https://oransi.com/collections/truecarbon-air-purifiers) Or my personal do-it-all favorite is the Alen Breathsmart 75i, filters and has an active carbon option. The only downside to these is the carbon seems to only last 6-9 months and filters are over $100 but it's a price I'm willing to pay with how quiet and set and forget these are..
