Over the last few years, there has been a lot of talk about air purifiers as an alternative to improve the air quality of indoor spaces when natural ventilation is not possible, especially as a result of the pandemic.

But these devices already existed long before and offer many other benefits: for example, they eliminate pollen and mites from the air, trap particles responsible for bad odors and pollutants produced by such everyday tasks as cooking. Hence, they are highly recommended in homes where there are people who are allergic, asthmatic or have respiratory problems.

How we have chosen and tested the products

Although I had never thought about having an air purifier at home, since the pandemic my mentality has changed and I believe that it is a device that can be very useful for eliminating viruses, allergens and even certain odors from the environment. To test them, I have taken certain aspects into account: closed windows, small or large rooms… and also the addition that a person in my house has been sick for a few days.

In addition to the purifying element, I also found it very practical that some of them had a heating or fan function, since, in some cases, it has helped me heat or cool the room in a few minutes (maintaining an adequate temperature). To test and evaluate them, I have taken into account the following characteristics:

• Design. Essential to be able to place them in a more or less central place in the room (recommended), the extension of its cable…
• Filtration. Type of filters used, their capacity to retain particles of different sizes and their performance.
• Clean air delivered rate. Fundamental to determine the size of the rooms for which they are suitable.
• Maintenance. Ease of changing filters, cleaning, etc.
• Additional features. Its additional benefits are very varied.

With formaldehyde sensor: Dyson Purifier Hot+Cool Formaldehyde HP09

Who is it for: for those looking for a purifier that heats and cools the room.

Why we recommend it: This model has a solid state formaldehyde sensor. Formaldehyde is a colorless polluting gas emitted by furniture and resin-containing wood products such as plywood or chipboard, other insulating materials and DIY products such as paint, wallpaper, varnishes and also cleaning products. . And what this purifier does is destroy it continuously through a catalytic filter that does not need to be changed. It also has a HEPA filter that captures particles down to 0.1 microns.

During testing, I used it in the living room (about 30 square meters) and also in a smaller room. In both places I did it with the windows closed and with a person in the house who had a cold at the time. It is capable of rotating up to 360 degrees on itself, so it reaches all parts of the place where it is placed. Controlling the device is very simple, either through the remote control, by voice or through the application, with which you can control and monitor the air quality (in addition to knowing when it is time to change the filter). . In both the largest and smallest rooms we did notice a certain renewal of the air, since the atmosphere was not stuffy, with all the windows closed and with a person coughing for a good part of the day. It also has two modes: diffuser and night. The first is to purify without cooling the room and the second is to be used at night, silently. I tried both and the nighttime one seemed like a success, since I was able to sleep with my partner without fear of catching his cold, plus it is very quiet and you can barely notice that it is on.

Another aspect worth highlighting about this purifier is that it is capable of heating or cooling the room in both winter and summer. In my case, and since I have used it in winter, I have only tried the ‘hot’ function and I found it very comfortable to quickly heat any place in the house.

Its weak points: It has a fairly high price.

Temporizador: Cecotec TotalPure Connected MAX

Who is it for: for those looking for an economical purifier.

Why we recommend it: With a very affordable price, this purifier also has a heater or fan function to heat or cool the room in which it is placed while purifying the air. In heating mode it offers a power of up to 2,000 W while in fan mode it reaches up to 45 W. Regarding its design, it is somewhat different from the other models analyzed; It reminds me of the shape of a small electric stove. However, it is light and beautiful, so it looks good anywhere in the house.

In the purifier section it has a HEPA13 filter (includes a replacement) with which it purifies and renews the air. This model rotates on itself up to 80 degrees and during the tests I tested the purifying mode with the heating mode (since it can be used at the same time). The heat it transmits is very pleasant and not at all annoying, since it has a thermostat: it is capable of detecting the temperature of the room and from there selecting the desired temperature (up to 30 degrees). For its part, the air (I tested it mainly in the living room and bedroom) felt much more renewed. It offers 14 speeds, several for heating mode and others for fan mode. It also has three preset modes: sleep, turbo or silent. On the test days, the one I used the most was the silent one, while working at home, and it really seemed like it wasn’t on. The turbo is a bit noisy, for example. Another thing that I liked about this model is the ease of handling it: a very easy to use touch control on the device itself, via remote control or through a Wi-Fi connection with the mobile phone. It also has a timer of up to 8 hours. In my case I used it to program it shortly before arriving home or while we were sleeping.

Its weak points: Turbo mode is a bit noisy if you need to concentrate while it’s on.

Voice control: Xiaomi Smart Air Purifier Elite

Who is it for: for those who want to purify and eliminate odors in the environment.

Why we recommend it: According to the manufacturer, it is capable of eliminating the flu virus in the air thanks to UV-C LED technology and plasma in approximately 30 minutes. The truth is that I tried it during a few rainy and cold days when several of my nephews came home with sneezes and coughs. At no time did I have symptoms or get sick. Another interesting issue is that it eliminates allergens and bacteria present in the air, such as staphylococcus aureus, and odors thanks to activated carbon with a high iodine index. In that last case I have to say that I noticed it a lot, since I have a dog at home and, sometimes and even if I ventilate well, a certain smell of the animal is noticeable. As for air purification, this time I tried it in the living room and kitchen. In the living room, and according to the manufacturer, it is capable of renewing the air in about 10 minutes, while in smaller rooms, such as the kitchen, it does so in less than 4 minutes. In the kitchen I used it, in addition to renewing the air, to clean it. In that case I did notice a difference after putting it in, since the kitchen is a room that usually has a very characteristic smell due to the daily cooking of food or the garbage can itself.

To control it, it has a fairly intuitive LED screen that shows the air quality in different colors and in which you can also change the mode (automatic or sleep, which is used at night), among other parameters. It can also be controlled by voice (Alexa or Google Assistant) and through the brand’s application.

Its weak points: nothing remarkable.

Two levels of filtration: Rowenta Eclipse 3 in 1 QU5062

Who is it for: for those looking for a silent purifier.

Why we recommend it: It has a striking design and, In addition to purifying, it also works as a heater and fan. The purification of the environment is carried out using two H13 HEPA filters and two pre-filters, which are the ones that block the largest air particles such as dust, human hair, pet hair… and which must be changed once a year. During the tests, I found the purifying function very satisfactory, since we noticed the air in the room where I used it, living room and bedroom, with a more refined and clean sensation (without seeing specks of dust in the air or hairs). as a pet, above all). It is quite quiet (31 dB) and when it comes to using it, it is very simple: it has two automatic modes, for day and night, which are controlled by a very intuitive touch panel, or by a remote control, which is included. . One thing that I really liked about this model is that you decide the oscillation of the device: from being fixed and not moving to reaching 90 degrees of movement. For their part, the heat and cold functions are very practical for heating or cooling a small room in a few minutes, providing very comfortable and pleasant heat or coolness. It also has a timer.

Its weak points: Its strong point is purifying, while the other two functions, fan and heater, seemed like a complement to me.
