Classic 205

**UPDATE:** After doing more research, I decided to go with [**BLUEAIR 2-in-1 Purify + Humidify**](https://reddit-links.com/BLUEAIR2in1). It seems like the most reliable option for long-term use and has good coverage without being too noisy. Thanks to everyone who shared their experiences, it really helped me make a choice. I’m looking to get a humidifier that actually makes a noticeable difference in my home without being a hassle to maintain. I want something that keeps the air easy to clean, and doesn’t create too much noise. I need a unit that can handle multiple rooms or has decent coverage. I’d also like one that feels durable and reliable long-term, rather than just a cheap gadget that stops working after a few months. For those who’ve used them, which humidifiers have been genuinely worth it? Durable and easy to maintain?

Not one mention of BlueAir. I thought those were once considered pretty good.

Please read the AutoModerator comment. Air purifiers aren't good at reducing *visible* dust as it's larger and heavier than "invisible" pollutants like PM10 and PM2.5. The same goes for pet hair. Sans is terrible. Shark is mediocre. Avoid both. Coway is generally one of the highest quality consumer-grade brands. Winix is good, more mid-grade. Blueair has an always-on ionizer. Some people want to avoid this because of possible health effects associated with ionizers or changes in gaseous air chemistry. Per the AHAM 2/3 rule, a space 600-800 sq. ft. needs minimum Clean Air Delivery Rates (CADRs) of 400 CFM - 534 CFM. Unfortunately your budget doesn't support a single large or multiple conventional HEPA purifiers. (An example that meets CADRs would be the [Coway Airmega ProX](https://cowaymega.com/products/airmega-prox).) If you still want a conventional HEPA purifier, go with the [Winix C909 at Costco](https://www.costco.com/p/-/winix-c909-4-stage-air-purifier-with-wi-fi-plasmawave-technology/100842491). It's a bit of an energy hog (95 W) and somewhat loud on the highest setting called "Turbo" (60 dBA per the Decibel X Android app), but it's good value for money. The C909 has PlasmaWave, a bipolar ionizer. You may want to keep this off if you have pet birds. Another option may be the [AirFanta 3Pro](https://air-fanta.com/products/airfanta-3pro). It uses Efficient Particulate Air (EPA) E11 filters, which is two filter classes below HEPA H13. Top composite CADR is 413 for the CARB Edition. Price is $159.99. Keep in mind CADRs listed by purifiers apply to the highest airflow speed/setting only. Lower settings have lower CADRs which reduces cleaning effectiveness.

Living in the U.S. and need an air filter primarily for dust and pet-related odor/hair/dander. I live in an 1,152 sqft apartment with 9’ ceilings (room i’m putting the air purifier in is \~500 sqft) Currently narrowed my search down to 3 options: BlueAir Blue Pure 511i Max ($112 on Amazon) Levoit Vital 100S-P ($120 on Amazon) Winix C610 ($99 at Costco) Which of these would be best? Are there any better options around this price point or lower that I might be interested in? I’ve been using a crappy $20 chinese amazon glorified essential oil fan that broke within 5 months so hopefully of these is better.

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.***
