Dyson company was established in the United Kingdom in 1991 by British inventor and entrepreneur James Dyson. The company designs and manufactures air purifiers, vacuum cleaners, heaters, hand dryers and such.
Dyson air purifiers known for several reasons. They are not your conventional air cleaner, but also heaters and fans combined. If you are looking for such multitasking air purifier you’ve stumbled on the right page.
Secondly, unlike Winix, Coway, Honeywell and many other air purifiers Dyson do not use True HEPA filters in their machines. Instead, the company uses standard HEPA filter in the older models and 360° Glass HEPA Filter in the newer ones. If you are looking for a True HEPA air purifier, Dyson isn’t there to help you.
The Dyson company claims that CADR rating is a useless metric since it mostly used as metric to determine speed of clean air delivery and not the metric that checks how clean the air actually is. They are not the one claiming that – Molekule air purifiers designer claims the same. Maybe the reason for that is that their CADR ratings are really, really low for the price they ask for their products and you want find the official CADR specifications on their website or Amazon. So I am going to leave this statement on their own head. If you are looking for an actual allergen removal air cleaner take a look at iQAir or Tracs air purifiers that are hospital grade and actually destroy viruses and bacteria.
Finally, all Dyson purifiers have WiFi capabilities and can be controlled via app or a remote.
On this page I review the best Dyson air purifiers available on the market today.
Dyson Pure Hot+Cool Air Purifiers
Dyson Pure Hot+Cool air purifiers stand for air cleaner, heater and fan. They are more expensive compared to the other air purifiers designed by the Dyson company.
Dyson Pure Hot + Cool Air Purifier HP04
Dyson Pure Hot + Cool Air Purifier HP04 is one of the best Dyson air cleaners out there. It is recommended for spaces up to 800 sq. ft. in size, consumes only 40 Watts of power in fan & air purifier modes and at the maximum speed produces 62 decibels of sound which is similar to a conversation in a restaurant. If you intend to use the Dyson HP04 as an air heater for most of the time, bear in mind that is will consume 1500 Watts of power at the maximum speed (there are total of 10).
Now let’s take a look at the air cleaning capabilities of this air purifier. The official CADR rating (it’s not listed neither on the official website nor Amazon, but available on BestBuy) stands for 80 cubic feet of clean air delivered per minute. If you compare it with the Winix 5500-2 or Coway Airmega AP-1512HH Mighty that have 4 times higher CADR rating but priced way lower than the Dyson HP04 you might ask why you should pay over $700 if you can get the better results with the cheaper air purifiers?
The most reasonable answer would be is that the Dyson’s HEPA and Carbon air filter is twice the size of Winix’s: 769 cubic inches compared to the 304 in3. So despite lower official CADR rating, the HP04’s filter can capture twice the number of pollutants and odors the Winix 5500-2 does. And the Dyson’s filter square footage is more than double in size compared with the Coway’s: 769 cubic inches vs 312 in3! Add to that 657 cubic feet of air moved at the maximum speed and the Dyson Pure Hot + Cool HP04 air purifier doesn’t look so bad. You can play with the number of air changes per hour using this ACH calculator.
As for the smart functions, the HP04 is packed with them:
- Auto mode uses sensor to detect air quality and adjust fan’s speed accordingly;
- Works with Alexa voice control;
- Can be set up to run airflow backwards;
- In Night mode LEDs and display are dimmed and the air purifier runs silently consuming several watts of energy;
- Timer to set up when you want the machine to run;
- The air purifier can be controlled via an app (requires iOS 10 or above & Android 5 or above) or a remote.
In conclusion, the Dyson Pure Hot and Cool Air Purifier HP04 is definitely not the cheapest air purifier out there, but it definitely one of the best reviewed here.
Dyson Pure Hot + Cool Link Air Purifier HP02
Dyson Pure Hot + Cool Air Purifier HP02 is an older model in the Dyson’s line-up of 3-in-1 air purifiers, heaters and fans. The main difference compared with the HP04 is the smaller HEPA and Carbon air filter (614 in3 in size). Other functions like auto & night mode, Alexa voice control and WiFi are present. The version without WiFi capabilities does not have ‘Link’ in the name and aren’t available on the market anymore.
The HP02 retails at $599, but it is often sold at a discount. If you want to have an air purifier for your living room, bedroom or kitchen below 400 sq. ft. this is a pretty good air purifier to consider buying.
Dyson Pure Hot + Cool Air Purifier HP01
The HP01 lacks auto mode, Alexa and WiFi support and in general it performs worse compared to the newer HP04. When it comes to price, this air purifier costs a little over 600 USD and the price difference between it and the newer model is approximately 150 bucks. I do not recommend buying the Dyson Pure Hot + Cool HP01 unless it’s available at a huge discount.
Dyson Pure Cool Air Purifiers
Dyson Pure Cool TP04
In my tests the Dyson Pure Cool TP04 improved the PM2.5 (measures fine particulate matter down to 0.3 micron) index from 7.4 to 0.2, PM10 index from 12.1 to 0.2, reduced total particulates from 599 to 14 and improved Air Quality Index from 30 to 0 (the lower the number means the better air quality overall). 14 remaining particles account for 2.33% from the initial 599, so I’d say this is pretty good result considering the low official CADR rating.
When it comes to the smart functions, they are identical to the Dyson HP04 reviewed previously and include:
- WiFi & App support
- Alexa voice control
- Auto & Night modes
- Backward Airflow Mode
If you aren’t interesting in the heating capabilities, I strongly recommend getting the Dyson TP04: it has the same power consumption and noise level, but available at a more favorable price. The air purifier has high airflow despite having low official CADR ratings (it also utilizes the same air filter installed in the HP04) and is perfect for large rooms.
Dyson Pure Cool TP02
Compared to the TP04, TP01 shows worse results in capturing small particles. In my tests the Dyson Pure Cool TP02 improved PM2.5 index from 2.8 to 0.2 and PM10 index improved from 4.1 to 0.2. Total particulates were reduced from 279 to 29 (90% effectiveness). The Air Quality Index improved from 11 to 0. It uses older design and filtering system, so that’s why it performs worse.
If we take into account the negligible price difference, I strongly recommend getting the newer model. Unless you find the TP02 below the $400 price tag, better take the Dyson air purifier reviewed above or the older TP01.
Dyson Pure Cool TP01
Dyson Pure Cool TP01 lacks all smart features the reviewed TP04 has (Alexa, WiFi, Auto mode), but it is way cheaper and often sold at a discount. If your home isn’t exposed to heavy pollution (cars, industrial pollution, etc.) and you keep your house clean for most of the time, saving up some money on the air purifier may be worth it. Power consumption difference is negligible (adds a few additional bucks per year) and the replacement filter is also cheaper.
Dyson Pure Cool DP04
Dyson Pure Cool DP04 is quite similar to the TP04 air purifier: it has the same HEPA/Carbon filter, but different design and the fan is more powerful as it can move 887 of cubic feet per minute compared to 614 CFM of the TP04.
However, in my tests the Dyson Pure Cool DP04 showed worse results in reducing pollutants in the air: PM2.5 index was improved from 4.9 to 0.3 and PM10 index improved from 8.5 to 0.3. Total particulates were reduced from 359 to 29 (92% effectiveness). The Air Quality Index improved from 20 to 0.
The results are worse compared to the Dyson TP04 air purifier, so if saving 50 dollars isn’t the top priority for you, I recommend buying the TP04 model.
Discontinued air purifiers: Dyson BP01, DP01, HP07, HP09, PH01.
