In today's increasingly serious air pollution situation, many people choose to install an air purifier at home to ensure clean indoor air, thereby ensuring the health of their families. Although many people have purchased air purifiers, it is undeniable that there are still many people who have doubts about the use of air purifiers, and there are many rumors that the use of air purifiers is not good. In order to give everyone a good understanding of air purifiers, we will explain some of the problems of air purifiers for everyone.

Does it work - can an indoor air purifier filter pm2.5?

The main material used to filter PM2.5 is HEPA filter, and its service life is between 6-8 months. This increases the cost of using the air purifier. Some people spend a lot of money to buy an air purifier on impulse, but they think that the maintenance cost is too high, and they do not change the filter as required. Buying a piece of furniture has no use other than taking up space.

The truth: In fact, we  have calculated that the price of a high-quality HEPA filter is about 400-700 yuan (different brands and models), based on an average use of 6 months, the daily cost of HEPA use It is only less then $0.5 . Compared with our health, this amount is definitely not huge.

However, there is indeed a problem that some consumers neglect the maintenance after purchasing the air purifier, but it is too rude to deny the ability of the air purifier to filter PM2.5 for this reason.

Do room air purifiers work - can room air purifiers cover an entire room?

The air in ordinary houses is not introduced from the tuyere that introduces air outside, but is sent into the room after being filtered, sterilized and heat exchanged by the fresh air tuyere, but is entered through doors and windows. Air purifiers require air convection, and one of the most intuitive indicators to determine the purification speed is the ventilation rate. The air purifier is placed in the corner, and its purification range is generally about 2 meters in diameter. In this way, it is difficult for the air in other places to be "captured" by the purifier. Some foreign air purifier manufacturers often choose to sell them when users are decorating their houses, and they will plan and design the entire house structure reasonably according to their needs.

TRUTH: Air purifiers have a CADR value, and air purifiers work best when their operating range is less than this value. If you choose an air purifier with a small CADR value in a large room type, it will naturally not be able to achieve the best effect. Not only that, when purchasing an air purifier for a multi-room home or connecting room, it is often necessary to choose a machine that goes with the person or a combination of multiple purifiers to effectively purify the air in the entire home.

Do Indoor Air Purifiers Work - Do Indoor Air Purifiers Create Secondary Pollution?

At present, air purification using electrostatic dust removal technology on the market is also a product recommended by sales personnel in major supermarkets. Electrostatic dust removal technology uses anode discharge to positively charge particulate pollutants in the air, and uses Coulomb force to adsorb the charged particulate pollutants on the dust collection device to purify the air. However, there is no way to eliminate bacteria on particulate pollutants using this technology, and ozone will be generated during the use of positive corona release. The half-life of ozone is more than half an hour. Ozone is an irritating gas to the lungs and can cause asthma. , cough, chest tightness and other symptoms.

Some air purifiers may also generate some new potentially toxic pollutants, or may re-spread previous pollutants. For example, purification equipment using HEPA and activated carbon filtration can easily become a breeding ground for microorganisms because the filter element is not easy to replace in time.

The truth: Some electrostatic precipitator air purifiers do have a certain ozone emission problem. However, only if the ozone emission exceeds a certain standard will it cause harm to the human body. Not only that, many physical air purifiers do not have this problem, which has also been well proved in the actual use test of Xiaobian.

It is undeniable that due to the lack of relevant industry standards, there are indeed some inferior products with poor performance in many air purifier products, but this does not eliminate the role of such products. As the most effective way to solve the problem of indoor air pollution so far, the air purifier is not just a simple comfort machine. The right choice and use can make it play the biggest role and achieve the purpose of improving indoor air pollution.
