STARKVIND

Ikea has their Air Purifier (either as a standalone or as a table), that can connect over zigbee. I had a little trouble at first with it, but I remember that someone had made a driver for it.

I use a Winix C545 and IKEA starkvind purifiers. They’re decent and the Winix filters aren’t very expensive. Still RabbitAir makes some of the best purifiers out there and they’re expensive but Google says there is a HA integration for some of them. If I could spend the money I’d buy one for sure.

I’m using the starkvind with ZHA and have full functionality too. It’s 100% reliable.

I looked for a zigbee one and the only one I found was the IKEA purifier - It is relatively cheap compared to some and the filters are cheap too.

mine is the other one - they are the same unit in a different form I think.

IKEA Starkvind was the only one I found, I wanted ZigBee though and works perfectly with z2m, the filters are quite cheap too

I have one too - It was the only zigbee air purifier I could find on the market. The air filters are quite cheap too, I am not sure the optional carbon one does much so I stopped using those. I did have an automation to tame down the fan speed, but I stopped using that and just let it do it's thing on auto now.

i just purchased a Starkvind in IKEA for $200 aud. It is not HEPA 13, but i dont need hospital grade stuff. the filters are $19 to be changed every 6 months. You cannot beat the long term price. It is good looking, big, very clever and silent enough.

Not much. Easiest explanation is this. So HEPA filters are tighter. Which ofc means that it catches more particles in one go, but EPA12 filters, because they are looser than HEPA, can pass more air through its filters. So for the same given power output, you are cleaning more air - and in each pass, EPA can also catch almost the same stuff that HEPA catches, but at lesser amounts (but it gets more passes of air for the same power output). There's quite a lot of discussion between HEPA and non-HEPA filters in this sub itself if you are interested in a more thorough reading, but the essense is, unless you are building a hospital style clean room, HEPA is probably overkill anyways. I own multiple units of the Uppatvind that I keep in multiple small rooms. They work great for small rooms, bringing the AQI way down. I also have one Starkvind for my living room since its bigger and it does the job. I don't have the table version though but its essentially the same thing - so if you want an airpurifier but anyways also want like a side table, then its a good idea. So if you are buying an Ikea air purifier, I'd either recommend the small uppatvind or the big starkvind and I'd recommend staying away from their mid size variant fornuftig. That one is in my opinion way too loud at the highest setting for what its worth.

Have you looked at the offerings at IKEA? The [Starkvind](https://www.ikea.com/de/de/p/starkvind-luftreiniger-weiss-smart-50461942/) costs 120€ and afaik uses Zigbee. If you just want to start them for a while, when your air is bad, you could also just get an air quality sensor (e.g. Alpstuga) and then control a dumb air purifier with a smart plug.

Besides the merv bases custom filters I would recommend IKEA Starkvind. In my research they are unbeatable for the running costs. No true HEPA, but that only matters for non recirculating use. 

Depends on the allergen. If the allergen is pollen, keeping windows closed more often and using an air purifier will help a lot. If it's something in the bedding like dust mites, mold or pet dander, another approach would be required (hot washing, hot drying, perhaps dust mite covers, etc). Go to r/allergies for ideas on how to figure out what the allergy is and how to manage it. Regarding air purifiers - they don't vary greatly in "quality" per se, as the fancier features like ozone-production or activated carbon are mostly just marketing. Even the 'grade' of the filter doesn't really matter as long as its HEPA or MERV rated - a filter that allows more particles through also allows more air through, meaning the air can pass through it more times per hour resulting in roughly the same level of purification. This is why [Corsi-Rosenthal boxes](https://en.wikipedia.org/wiki/Corsi%E2%80%93Rosenthal_Box) cost ~$100 and outperform purifiers costing 3-4x as much. Selecting an air purifier to buy is mainly a trade off of how much air you can pump through the filter for a given loudness. Increasing the filter size decreases the loudness for a given throughput. Therefore, you want to buy a big cheap air purifier that is efficient with energy and has cheap filters available. The IKEA Starkvind is one of the best on the market. It comes as a table or freestanding option, the filters are cheap to replace, it's quiet at lower settings because the filters are big and it's fairly efficient. If it's a small bedroom, the smaller IKEA purifiers are also good value.

The Ikea Starkvind also works nicely with ZHA. It's been running here for over a year now. It's a great device, and works well as a fan, too. I agree with your take on the built-in auto mode, but it's not really an issue for me in daily life. I automated it "better" in combination with Apollo Automation's Air-1 sensor.

I have a few of IKEA’s [Starkvind](https://applink.ikea.com/tY8M9r9M4w--20501954--gb--en) smart air filters. Two of them that are built in to side tables and one freestanding in the office. They definitely do help remove particulates and contaminants from the air. Filter replacement they recommend every 6 months but I put that to 12 months with no issues. I have one in my bedroom which runs on the lowest setting constantly and you can’t hear it at all. The other in the kitchen/diner is left on auto and when it kicks up a gear (usually when cooking) you can definitely hear that, but once it’s cleared the air it ramps down again pretty quick.

I picked up a couple of the IKEA STARKVIND units, they have some that are integrated in to side tables which is a bonus and they automatically ramp up names on either their internal sensors and you can trigger speed changes via an external air quality sensor if you like.
