This makes them great as *replacement filters for other air purifiers*. This is one of the things I love the most about IKEA - hackable IKEA products are available worldwide and can be easily sourced and adapted as &amp;quot;materials&amp;quot; instead of &amp;quot;products&amp;quot;.&lt;p&gt;The Starkvind air purifier appears to be airflow-constrained on the fan, and not the filters they used. I put its filter (with some cardboard glued to the edges to seal the difference in size) in a Coway Mighty AP-1512HH (often recommended) and have not noticed a huge decrease in airflow at all, even though technically there is less filter area. Based on rudimentary measurements with an anemometer, the airflow is acceptable, and after about a year or more of continuous use, it&amp;#x27;s lost about 10% of the airflow after I recently changed it.&lt;p&gt;Even better, if you are so inclined, you can buy several STARKVIND filters and cut them to size&amp;#x2F;merge multiple if your purifier takes different size filters. And if you have a smaller purifier, IKEA also has the FORNUFTIG (thinner) filter for $7 that you can similarly hack.</text><parent_chain><item><author>Mister_Snuggles</author><text>I really like this purifier&amp;#x27;s big brother, the IKEA STARKVIND, which is available in both regular[0] and table[1] versions.&lt;p&gt;The table version is nice because, assuming you place it somewhere you want a table, it takes up no room.  The regular version is awkwardly large, so placement is a bit more of a challenge.&lt;p&gt;The killer feature for me is that its air quality measurements and controls are all exposed via Zigbee, and it works very well with Zigbee2MQTT and Home Assistant.&lt;p&gt;Related to this, IKEA has recently brought out the VINDSTRYKA[2] air quality sensor.

Very, very nice thing to have in a kitchen, if you&amp;#x27;re a smoker or if you have cats. The carbon filter takes out &lt;i&gt;a lot&lt;/i&gt; of nasty smells, enough to not smell anything food-y even in a directly adjacent room while running a frying pan and chopping onions, or when smoking a cigarette on the open window. And the &amp;quot;plain&amp;quot; filter picks up a loooot of the fur that you&amp;#x27;d find everywhere including in your food when your cat decides it&amp;#x27;s time to go and shed everywhere she can.</text><parent_chain><item><author>Mister_Snuggles</author><text>I really like this purifier&amp;#x27;s big brother, the IKEA STARKVIND, which is available in both regular[0] and table[1] versions.&lt;p&gt;The table version is nice because, assuming you place it somewhere you want a table, it takes up no room.
