We paid around £150, I have asthma, live in an old house so more dusty and have to dogs that shed, it has honestly made such a difference but it has HEPA and Carbon filters which I think why it’s so good.
The 2 filters need changed approx every 6 months at a cost of around £100 for both, it actually has 3 filters but one can be hoovered so when that one does need changed it another £30. I’ve just checked and the price has gone up for the actual purifier it’s now £179 from the site I got it from.
Zero-S would be enough for multiple bedrooms of that size, which far exceeds your goals for the necessity of this purchase. In NL, Zero-S is currently 150€ so that's interesting... but either way, that would be the reason for 3x the price.
>I did notice a difference though with the purifier set on max speed for an hour with the door closed, which is a plus.
Smells are not purely about some particle count in the air, or the density of it. Your brain has the ability to de/increase the sensitivity to it both consciously and subconsciously. That's why 'odour reducing' is just marketing. Either way, you're comparing a goliath model to a mouse -- they serve different purposes.
Avoid Sans and Shark. Both are mediocre at best and use deceitful marketing.
Blueair performs and is reviewed well. However, all of their units feature an always-on ionizer to charge the mechanical filtration media. Some people want to avoid this as there could be changes in air chemistry or possible negative health effects.
Clean Air Delivery Rates (CADRs) are an important metric gauging cleaning effectiveness.
For rooms in meters, ceiling height is very important. CADRs should be *at minimum* 3 times the room's volume in m^(3). I'll assume a height of 2.4 meters for calculations.
* Room 1: 108 m^(3) × 3 = minimum 324 m^(3)/h CADR
* Room 2: 66.48 m^(3) × 3 = minimum 200 m^(3)/h CADR
For each room, you could buy the [Winix Zero-S](https://winixeurope.eu/en/air-purifiers/air-purifier-winix-zero-s/) (top CADR: 390 m^(3)/h) or the [Winix T800 WiFi](https://winixeurope.eu/en/air-purifiers/air-purifier-winix-t800/) (top CADR: 500 m^(3)/h).
Both models have PlasmaWave, which is an optional bipolar ionizer. If you have pet birds, keep this off as it could harm them. Note: PlasmaWave turns back on after a power off/on cycle.
Keep in mind the CADRs listed for purifiers apply to the highest airflow speed/setting only. Lower settings have lower CADRs which reduces cleaning effectiveness.
Hello! I'll address u/ialwaysmisspenalties here too since they raised similar points.
First: when writing my initial comment yesterday, I could have sworn the Coway Airmega 150 was £149.99. 🤔 But could have misread it.
As for recommending Coway over Winix, it's because Coway is higher quality and tends to be a little quieter. Some Winix units develop bad motor bearings after the 2 year mark. This can manifest as a whining, whirring, or clicking sound.
Winix's PlasmaWave and Coway Airmega Mighty's Vital Ionizer are bipolar ionizers. These are cheap means of enhancing one or more particulate CADRs. Any Winix or Coway model with an ionizer will be certified for very low ozone emissions via the [ECARF Directory](https://www.ecarf-institute.org/en/certified-products-services/).
Some people opt to switch the ionizer off or avoid models with ionizers as they can interact with gaseous air chemistry or possibly induce negative health effects. People with pet birds should avoid ionizers or always keep the ionizing function *off*.
In short...
* The **Winix Zero-S** is very good value for money; I'd prefer this over the 5500-2. The Zero-S doesn't have a child lock.
* The **Coway Airmega Mighty** is very good value. However, it's louder than other Coway models, isn't terribly energy efficient, doesn't have activated carbon pellets, and lacks a child lock feature.
* The **Coway Airmega 150** has a lower top CADR, but will be quieter than the Winix units and the Coway Airmega Mighty. It lacks a child lock.
* The **Coway Airmega Jet** has a child lock, high top CADR, and is energy efficient. But it's the most expensive.
I'd also research filter replacement costs from Winix / Coway and various stockists.
No way I got this same one for my friend when he got back from the hospital after being diagnosed with leukemia bc he needed his air clean for a while. Glad I picked well!
Hi everyone! We have discovered toxic mold in our basement behind walls. We are getting remediated next week. In the meantime, I bought a winix c353 for the first level. Our home is average size. I’m tired of moving it from living room to bedroom so I am looking for another one for bedroom only which is about 20x20. Ive turned AC unit off and basement is sealed shut with plastic until remediation. Thank you!
