Customer Ratings & Reviews

Really impressed with the PH04. Humidifies and purifies my 800 sq ft basement without issue; it always smells so fresh down there. I’ve noticed my psoriasis clearing up and allergies have improved significantly. Connecting to the app on my phone was easy and I enjoy all the control it gives, plus the info on the LCD screen. Filling up the tank and running cleaning cycles despite having hard water is easy too. I have another Dyson air purifier that’s over a decade old, still going strong, so I’m not worried that I’ll have this for years to come.

Since I purchased the Dyson Purifier Humidify + Cool Formaldehyde PH04, I couldn’t be more satisfied with my purchase. The design is simply outstanding and very elegant, making it look fantastic in any space. The purifier and humidifier functions are truly excellent, doing an impressive job of keeping the air clean and comfortable at my room. While the price might seem a bit high, considering the reliability and quality that the Dyson brand represents, I believe it’s a worthwhile investment. Moreover, the app is super easy to use, making it incredibly convenient to control and customize the functions. I’m very happy with this purchase!

Good quality air purifier with humidity. Quiet sound didn’t disturb when sleep. Nice design and compact best in every location it can cover. I use in my bedroom, make air freshener and flow smell quality of the air.

It best buy ever, the air quality at my house is very fresh and clean,I have 6 cats, and I cook a lot you will never notice the smell. Also me and my daughter we have asthma and help a lot too,

Was a little off by the price and the size but once it arrived and was hooked up we were hooked this Dyson product is everything you would and should expect the sensitivity is truly amazing you put perfume on it knows you cook it knows the humidifier built in is so worth it we put it on AUTO and walk away . We live close to a PORT and the air quality is not that good we already can tell a huge difference just in housekeeping much much less dusting and it offers so many features

This is an amazing machine. definitely noticed a huge difference with the humidity level in my bedroom after it's been running for about two hours. After reading all the negative reviews I was a little nervous about purchasing this but it was on sale and since I'm a total plus member I get a two year warranty and I wanted an all in one unit and it fit the bill. So far no issues whatsoever and it's a very well built machine. I have it set to a nice white noise level for sleeping. I like it so much I might get another one

At $900, so far I’m disappointed by the quality. With my first unit the mechanism that controlled the oscillation failed after a couple weeks. I haven’t even fired up the replacement unit yet because after unboxing I noticed some nicks below the screen. Not a huge deal but this is a brand new $900 product. Now I have to decide if it’s worth hauling another unit back to Best Buy (it is big). When working the unit was good with nice app features and functionality. But if you read reviews of prior generations there seem to be a lot of issues similar to mine with regard to quality and durability. Best Buy was very helpful with the initial exchange.

This is my 2nd purchase of the dyson purifier+ humidify + cool formaldehyde machine, one for my downstairs family room and the 2nd one is in my bedroom, it helps with my breathing issues.Dyson is the best

Have several Dyson purifiers and humidifier but this one is the best so far. Been working great and keeping the air clean and the humidity just right. Highly recommend.

[Employee of bestbuy] Works really well, came in handy during the Canada wildfires that sweep through NY. A bit pricey, but offers piece of mind and fresh breeze

Very ausem device now my wife and breathe well the hall room is well ventilated

What else can we say? Highly easy to use, does exactly what it advertises. Yes it's expensive, yes it's worth the price. Our Bedroom has a 70% humidity level now and we no longer have a dry feeling to our bodies. Finally a restful night's sleep in the dry climate of New Mexico

I love when i put on auto and it goes crazzyyy like R2-D2 and starts spewing fresh clean air in different patterns and even controls humidity. I had to have it. Why the bronz color?

Dyson's PH04 is the new product that Dyson released in Nov 2021. This is designed for people who are conscious about air quality and I am one of those customers. I have 3 Blueair purifiers that I run for most of the year to keep the dust and pollen out of my home and Dyson Purifier Humidify + Cool Formaldehyde™ PH04 replaced my living room purifier as it met my need at several levels - Humidifier + Air Purifier with HEPA filter (H13 - 0.3 microns spec!) + fan + system that destroys formaldehyde (irritant and is present in new homes/furniture/flooring). I spend $300+ per year on air purifier filters and hope to keep the cost down with Dyson's PH04 Humidifier + Purifier. Design: Appealing and stylish design compared to the bulky (on wheels!) air purifier system that I now want to replace. If you are an Apple fan you know what Dyson design means to you! Small foot print, weighs about 18 lb and can be moved around the house easily. Easy access to filters and water reservoir and not much cleaning needed other than replacing the filter and cleaning the reservoir and central filter when the warning shows up on the display. Slick remote to program the unit and great app to check the room conditions, air quality, history, etc. Unboxing and Setup: Setup was a breeze. Took less than 5 minutes to assemble and program the app to connect to the home Wi-Fi. Comes with a 2 year warranty. Can be controlled with Amazon Alexa, Google Assistant, and Siri. I let it run in Auto mode as recommended in the instruction manual and not worry about messing with the settings. It automatically controls the humidity level and adjusts the air flow to control the air purity inside the room. Features: Starting with basic features • Similar airflow controls if you own a Dyson fan. 10 speed settings, oscillators that guide the airflow, breeze mode, back airflow mode, night mode, etc. Quite operation when compared to fans or other purifiers! • Talking about the purifier itself, it has a cylindrical fully sealed HEPA H13 filter that sits inside the cylindrical grill. HEPA 13 is in the highest tier of HEPA standards that traps 99.97% of particles with 0.3 micron or more in size. Its medical grade filter! I have to see how long the filter (half the cost of my current purifier filter) lasts before I have to replace, to compare its maintenance costs with the ones I currently have. I am moving to Cali and definitely see the need to have more than one unit to keep the dust levels down inside my home. • Built in humidifier with a one gallon tank that can last 36+ hrs with continuous usage. It has a deep clean cycle that you can activate with touch of a button and it guides you through the process. It has UV cleanse technology that removes 99.9% bacteria in the water while it humidifies. No more standalone humidifiers that need constant cleaning! The app has pretty good information on the room humidity, air quality and its history. • This can also be used in summer as well as the humidifier functions as air cooling system. • Newer homes or remodeled homes with wooden flooring have to worry about formaldehyde which can cause skin irritation. The unit's catalytic filter traps and breaks it down to harmless byproducts and it doesn’t need replacing. Don't have to worry about formaldehyde for now as I use home testing kits to test the levels every three years, and unfortunately they are no set standards on what the acceptable levels are. Maintenance: The UV system and the deep clean cycle eliminates the need for major maintenance and changing the filters is a 2 min job. Comes with a 3 pack descaling kit Overall, I like the Dyson's 3 in 1 system and it pays for itself. It eliminates the need for owing a separate air purifier, humidifier, and a fan! The quality speaks for itself. Owned several Dyson products over the years (10+) and never had to fix or replace anything on those till now!

I've bought two of these machines because I loved all of my other Dyson products. These machines are not reliable and I've had to call Dyson support to replace the main pump column 3 times between the two machines in the past couple of years. I spent more time trying to get these to work normally than actually using them. They are absolutely not worth the premium and is the first big disappointment in Dyson I've had.

Great fan, only tiny issue is that I wish it had a built in heater too.

In love with this great product! Looks and functions great in my home.

A very good purchase for me. Breathing in clean air is a delight. I realized leaving my patio door open was not a great idea being that i stay in the city were the traffic is plentiful. If you can afford the ph04 you will know how great 1000$ air feel.

Works wonderfully helps so much with my childs eczema.

We rescue dogs , boy we needed clean air , yes this is absolutely the answer
