Dyson - Purifier Humidify+Cool Formaldehyde PH04

I have the PH01 and PH04, touch wood both units still work and I’m happy about its operation. The most important thing is, you MUST NOT put the pump cover upside down, otherwise the water may seep into the circuit board and cause most of the other issues. Also it designs to humidify a room, instead of an open space. You don’t need to use distilled water, but you need to clean the filter and pump with citric acid at least once a month with deep clean function to prevent scale build up. This is an evaporative humidifier so it will not have white dust issue. Hopefully you get the good unit to begin with.

I have been using the Dyson Pure Humidify+Cool for a while now as my air and purifier and it has been great for my similar-sized space. It effectively removes fine dust and controls humidity. Filter replacements are a necessity every 6-12 months and electricity costs are at a reasonable rate

As someone who is strongly allergic to cats and moved in with my now-wife, who has cats, I can tell you there’s plenty you can do! How strong is the allergy? If it’s mild, there isn’t much to worry about - clean the house regularly, make sure he keeps taking antihistamines, and that’s basically it. If the allergy is strong (like in my case), then you’ll have a real battle on your hands, but it’s doable. First, cleaning needs to become regular and in-depth: moving furniture, cleaning every corner, and routinely washing anything the cats touch. This includes mattresses, sofa covers, blankets, pillows, and other items you may have washed only semi-regularly in the past. Now it needs to be done every week, or more often. Get a HEPA vacuum cleaner; with two cats, you’ll be vacuuming a lot. Get a good air purifier/humidifier. The cheap ones didn’t work for me, but once we invested in a Dyson, it made a huge difference. It also helped to get a bigger flat so I have my own room that has no cats policy so I have my safe haven. Last but not least, my personal *hail mary,* sometimes the allergy is so strong that the only way to calm it down is to either leave the house for a few hours or use a face sauna. You can make your own with a pot, salt, hot water, and a towel over your head, or you can buy a commercial one. Regarding the comment "It's either me or the cats". I totally understand this comment as I had the same one when I was dating my wife. If he's strongly allergic, it's kinda natural he wants to prioritize his own health resulting in these extreme overexagarations. I was the same. So I'd say just try to live together a bit, fix what you can fix. If it still doesn't work, or he refuses to collaborate and can't accept the cats, then ditch him! :)

If you looking for filter out dust you need the one has big and powerful fan but if you need one to filter out VOC and a microscopic stuff you better of looking for multi layer filter system with HEPA , I have used Coway for dust and Dyson formaldehyde for microscopic and IQAIR multigas for road traffic pollution next to my apartment!

There is truly no "one and done" air purifier for dust, as dust is too heavy to be pulled by typical air purifiers. The Dyson formaldehyde air purifier attempts to solve this issue, but directing air at stagnat pockets within a room to encourage dusty air to make it way towards the filter intake. That'll most likely be your best bet against dust if you don't want to manually remove it, ie vacuum, brush, etc etc.

Why Dyson, they are literally the worst AP on the market

Low quality parts. They market well using fancy CGI but the reality is constant maintenance and very expensive cheap parts that fail even after 1-3months Dyson is the most talked about vacuum when it comes to failure and shoddy workmanship

My dad has one and like many customers he's never changed the filter or cleaned the pre filtration system.......it now blows meat flavoured air hahahaha

Same one I have, and I paid less than that for it new!
