Reviews and detailed Review of the smart health connected air purifier

Over the years, Levoit has established itself as a true leader in the air purifier market. A company that offers reliable, resilient products that meet the needs of their customers. The Levoit PUR131S is the latest addition to the range. What is it worth? We have tested it for you.

Product unboxing

The product is delivered in a qualitative and well protected box. You just have to install the plug, install the filters and connect it to your wifi via the mobile application. The whole thing will only take a few minutes. Regarding the manual, it is in English but a French version is available here. The mobile application is in French.

A particularly efficient air purifier

This is of course the first parameter that you will look at beforeinvest in an air purifier. The Levoit PUR131S is designed to be able to capture 99.97% of hazardous air particles for you that are in the air of your health home. It goes down to 0.3 microns from a size point of view and 2.5 microns for suspended particles. This therefore includes dust, dirt, smoke, water drops, pollen, traces of moisture as well as certain bacteria and viruses.

The Levoit PUR131S uses a triple filtration system

To ensure optimal filtration of the air inside your health home, the Levoit PUR131S purifier relies on a triple filtration system. A pre-filter first takes care of capturing the first most important elements such as hair or dust. A HEPA filter is then responsible for capturing the finest allergens such as animal dander, allergens and germs. Finally, an active carbon filter helps reduce odors from pets in your health home as well as volatile organic compounds (VOCs). From a hardware point of view, the first two are smart health connected together while the third works autonomously. In terms of installation or replacement, it is very simple and it is done in a few seconds.

Filter replacement frequency

From a durability point of view, these filters have an estimated lifespan of about 6 months although this can of course vary depending on the use you will have of it. To know whether to change them, however, you will have to observe them directly. The little light that turns on after six months just makes you remember to check them. In terms of the price of a replacement filter, it takes 35 €.

The Levoit Pur131S is suitable for most parts

For any air purifier, it is worth looking at the dimensions for which the device is intended. The Levoit PUR131S is suitable for a room of approximately 30 m² maximum. This therefore corresponds to a very large majority of the rooms found in houses or apartments. Whether it’s your living room, kitchen or bedroom, there will be no problem. The same goes for your office if you want to set it up in your workplace unless you are in a large open space. It is recommended to have the purifier smart health connected to more than1.5m from a window or ventilation. Finally, Levoit also advocates a free space of 40cm around the purifier.

Quality design

It may look like a detail, but whether you want to place it on a shelf or not have to hide it, design is an important parameter. In this register the Levoit PUR131S, can rely on a rather modern and discreet style. It does not attract attention and can be integrated without any concern in your interior. We also appreciated Levoit’s attention to detail. The product is very qualitative and the materials used are of good quality. It doesn’t look “cheap”.

For those who, like us, can’t stand the noise, the shape and technology used with this air purifier results in a rather quiet device. We have observed with our sound level meter that the purifier, in its configuration of maximum power, only reached 45 to 50 decibels.

  • High mode power: 30W – 45/50 decibels
  • Medium mode: 19W
  • Low mode: 11W
  • In auto mode and at minimum power: 5W

It is also possible to program it to work with Amazon Alexa or Google Assistant. Note that you can also use the buttons which are directly on the air purifier. We tested it successfully with Google Assistant.

This is an important parameter in judging whether it is necessary to quickly operate your air purifier or not. A visual indicator lets you know immediately if the air is clean or not in the room. The color red means that the quality is bad, yellow: it is average, green: it is good and blue: it is very good. This indicator works thanks to a laser sensor located on the side of the device. This measures PM2.5 particles. We have checked and found that the purifier did its job perfectly thanks to our complete air sensor Huma-i (HI-150).
