Philips - 3200i PureProtect

I have the Philips 3200 which is very good.

Dyson is the least effective and the most expensive. You're looking for around 600 CFM total, so 2 of the Philips 3200 should do it, however they would need to be on Turbo all the time which is pretty loud at 53 decibels. On Medium mode it's quiet enough but only produces 170 CFM, so you need 3-4 units to achieve 5 ACH. Usually air purifiers don't do much from the other room. Is this one large space or is it subdivided into rooms? That will effect how many air purifiers and which exact models. Avoid the Philips 3400, or any other humidifier that uses warm mist / cool mist / ultrasonic technology. The technology produces large amounts of air pollution (or in the case of the Philips, it clogs its own filter with the pollution it generates).

Purifiers don’t deal with dust. There is a stickied thread in this sub that explains the details. I don’t know what brands are available where you are, but generally you do not need the Dyson. It’s overpriced. Any appropriately sized unit from a reputable brand is going to be fine. HEPA is the standard, but there are brands that don’t use HEPA filters that are still good like Levoit and BlueAir. Again I don’t know what’s available to you, but other good brands include Phillips, Xiaomi, Coway, and Winix. More expensive brands include SmartAir and IQAir. Do not get any combo units, that is something that is a purifier that is also a heater or a purifier that is also a humidifier. They never work. If you want something quiet, you should buy a more powerful purifier than you need for the space so you can run it on a lower setting. All CADR measures are taken at top speed, which is also always the loudest. You can use this [calculator](https://housefresh.com/cadr-calculator/) to figure out what CADR you need for the room, and then just get a model that is more powerful than that which will deliver the cleaning you need at a lower speed. Hope that makes sense and if you have any other questions let me know

The room is large, so you need a CADR of 432 m3/hour to get the right number of air changes per hour to help with viruses. The Philips 3200 has a CADR of 520 m3/h, so it is big enough to clean the room, but you will have to run it on high the entire time. Do not run it on auto or sleep mode. The max decibel rating is 47, so it should be fairly quiet on high. If you find it too loud on high, you’d need to buy a second unit so you can both at the same time on a lower setting to get the same cleaning Hope that makes sense, and if you have questions let me know!

I have the Philips 3200 of those and for the price/performance I recommend it. The blueair if I remember correctly uses an ionizer for the filter so I would rule it out.

In Europe there is only the 4200 in black like mine and in silver (ac4221, ac4220). Of the 3200 there are 3 colors: brown like mine, black and silver-white (ac3210, ac3221, ac3220).

A Philips 3200 would be better; that one's for small spaces. The 4200 isn't worth the price. It's exactly the same as the 3200, just with a gas sensor and a filter with more carbon. (I have both.)

I would definitely avoid both Dyson and Shark-Ninja. Dyson has low particulate CADRs and a high price. Shark is mediocre quality and has very little capacity for gases, vapors, or odors. The Dyson Purifier Cool PC2 De-NOx may be good at reducing NOx and formaldehyde. However I don't know how well it reduces other gases *without* creating problematic unintentional byproducts. If you have high levels of particulates *and* gases/vapors/odors, you generally need two types of air purifier. This is because most common purifier brands have very little sorbent media for gases/vapors/odors. Instead, they're designed for particulates. Heavyweight sorbent media purifiers are very loud, very expensive, and clean the air more slowly than particulates-focused units. I would strongly recommend having air testing done with gas chromatography–mass spectrometry (GC-MS) analysis. GC-MS would tell you which gaseous species are present. This is because plain/chemically untreated sorbent media do not have high removal capacities for all gaseous species. Some people have reported problems with plain sorbents, such as "sweet" smell emanating from the purifier or spikes on tVOC monitors despite a reduction in odors. Unfortunately I don't think you have loads of sorbent media purifier options in Turkey. The only ones may be the IQAir GC and GCX series purifiers. The GCX series purifiers would have the most sorbent media by weight. # Particulates I'll recommend particulates purifiers for now. For rooms measured in meters, Clean Air Delivery Rates (CADRs) should be 4-6 times a room's volume (in m^(3)) where higher pollution levels or people with allergies are present. Bedroom should have CADRs of 192 - 288 m^(3)/h. Living room/kitchen area should have CADRs of 288 - 432 m^(3)/h. For your bedroom, I would recommend either the Philips PureProtect 3200 Series (AC3220/10 model) or the Levoit Vital 200S. For the living room/kitchen area, I would recommend the Philips PureProtect 3200 Series (AC3220/10 model). Keep in mind particulate CADRs apply to the highest airflow speed/setting only. Lower settings have lower CADRs, which reduces cleaning effectiveness.

Go for philips 3200/4200 series , both are same, buy whichever’s available, coway is good but like honeywell , it’s a task to find authentic filter as they use third party service vendor’s

And coway filter replacement is aroun 4000 but philips has dual filters so the extra cost , user wanted advice between the two, so philips

I don't turn it on throughout the whole day. I open the windows first to renew the air, clean etc and when everything is closed again, I let the purifier work. I bought a Philips PureProtect after a lotttt of research cause it's very effective, you can control it remotely and uses very little electricity, less than a light bulb!

I just got one as my parents house is super dusty and pollen-y and it’s changed my life. I used to always have a blocked nose or scratchy throat and my room felt stuffy - now it’s perfect. I got the Philips pureprotect purifier
