Are air purifiers really not an IQ tax?

My guy smokes a lot at home, but I don't smell of smoke at all. By the way, Baiwu Pure FC Qingya series air purifier is good.

Air purifiers, also known as "air cleaners", air purifiers, and purifiers, refer to products that can adsorb, decompose or transform various air pollutants (generally including dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.), and effectively improve air cleanliness, mainly divided into household, commercial, industrial, and building products.

There are a variety of different technologies and media in an air purifier that allow it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructured photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; The main material technologies are:

Photocatalysts, activated carbon, synthetic fibers, HEAP high-efficiency materials, negative ion generators, etc. Most of the existing air purifiers are composite types, that is, a variety of purification technologies and material media are adopted at the same time.

Passive purification (filter purification).

The main principle of the passive air purifier is to use a fan to pump air into the machine and filter the air through the built-in filter, which can mainly filter dust, odor, toxic gases and kill some bacteria.

The filter screen is divided into: dust collection filter, formaldehyde removal filter, deodorization filter, HEPA filter, etc. Among them, the relatively high cost is the HEPA filter, which filters particulate matter very effectively, and can play a role in decomposing toxic gases and sterilization, and can inhibit secondary air pollution.

2. Active purification (no filter type).

The fundamental difference between the principle of active air purifier and the principle of passive air purification is that the active air purifier gets rid of the limitations of fans and filters, and does not passively wait for the indoor air to be pumped into the purifier for filtration and purification, but effectively and actively releases purification and sterilization factors into the air, and reaches all corners of the room to purify the air without dead ends through the characteristics of air diffusion.

3. Double purification (active purification + passive purification).

This kind of purifier is actually a combination of passive purification technology and active purification technology. The filter is the core component of the air purifier, and its quantity and material have a great impact on the purification effect. At present, the air purifier filter on the market generally has only three or four layers, and some products have five or six layers.

Among them, there are five main types of filters for air purifiers, including pre-filters, washable and deodorized filters, formaldehyde removal filters, HEPA filters and humidification filters.

1. Air purifiers are not paying IQ taxes!

2. Most people buy air purifiers, and they do pay IQ tax!

Most of the air purifiers on the market are filter-type air purifiers, which have a good purification effect on dust removal and formaldehyde removal.

There are two main differences between the different air purifier products:

1. Different brands and different positioning, so they are different.

2. The filter screen grade is different. The higher the filter level, the better the purification efficiency, and the better the removal effect of ultrafine particles, viruses and bacteria, but relatively speaking, it is also easier to be blocked, and the filter element needs to be replaced more frequently, otherwise the secondary pollution is serious.

Most air purifiers have a certain purification effect on allergic rhinitis and formaldehyde removal.

Only high-efficiency HEPA filter purifiers equipped with H12 or above can have a good purification and removal effect for allergic rhinitis, asthma, bacteria and viruses, and ultrafine particles.

At the same time: the HEPA filter element must be replaced every 2-3 months.

Because the purification efficiency of the filter screen is decreasing rapidly, the secondary pollution is serious. The filter is adhered to various contaminants and can be easily blocked. If the filter is not replaced in time, then secondary pollution will be formed, and the consequences will be more serious.

There are 4 main indicators in the national standard for air purifiers: CADR, CCM, energy efficiency, and noise.

There are 4 main categories of indoor air pollutants:

1. Particulate matter PM10, PM1, the smaller the particulate matter enters the human body, the deeper the harm to the human body, the greater the harm to the human body, and a good air purifier must have a good purification effect on the finer particulate matter.

2. Viruses, bacteria and other microorganisms, especially indoor corners, ventilation pipes, and filters that are not replaced in time, are easy to form secondary pollution, and germs breed and spread.

3. Formaldehyde, TVOC and other gaseous pollutants. Formaldehyde is very reactive, with a release cycle of up to 5-15 years, so it needs to be removed continuously, rather than in a short period of time.

4. If you have pets at home, especially those with cats or dogs, animal allergens, animal hair, saliva mixed with dust and germs, etc., are stuck together, and a good air purifier must have a good effect of removing allergens.

Highly recommended: Finland Yawei fresh air purifier, super clean, ultra-pure air! 24-hour ultra-clean air!

1. Super clean, ultra-pure air! With an average colony count of 1, the air is cleaner than a clean operating room. Far beyond the HEPA medical high-efficiency filter purification level.

It can achieve a purification accuracy of more than 1nm (nanometer). Covers the conventional virus particle size, which is much higher than the HEPA high-efficiency filtration standard under the American and European standards. H1N1, H3N2, enterovirus, poliovirus removal rate, Staphylococcus albicans killing rate, Staphylococcus aureus killing rate, Escherichia coli killing rate.

2. No filter, no consumables.

3. Fresh air + purification + disinfection and sterilization, one machine with three purposes. Plug-and-play, automatic cleaning and maintenance-free. It is suitable for all kinds of houses before and after decoration.

Before I bought it, many people said it was an IQ tax, but I thought I'd have to try it. Counting my family's Shule's has been used for more than half a year, and the child's nose is indeed much less uncomfortable now, and it is estimated that it is related to the improvement of air quality after buying a purifier. If possible, it is recommended to try it

The air purifier itself is not an IQ tax, but there are some very expensive and complex air purifiers on the market, and these products are called "IQ taxes" by some people.

These expensive air purifiers often come with advanced features such as smart controls, multiple filters, air quality monitoring, and more, but not everyone actually needs or uses them. Moreover, some low-cost air purifiers are also able to achieve basic air purification results.

Therefore, when purchasing, you should choose the right product according to your actual needs and budget. Overall, an air purifier is a useful device that can improve indoor air quality, but it is not a necessity and needs to be treated rationally when buying. When buying an air purifier, you should compare air purifiers from different brands and merchants and choose the most reasonable products.

At the same time, it is necessary to pay attention to the fact that there may be quality problems with the ** that is too low.

Things to look out for when choosing an air purifier

1. Air purification effect: When choosing an air purifier, you need to pay attention to its purification effect, including the purification capacity of the purifier, the purification range, and whether it can remove air pollutants such as spring or round. You should choose a suitable air purifier according to the pollution level of your environment and the actual situation of your family.

2. Filter type: The type of filter of the air purifier is also a factor to consider. Common filters include primary, intermediate, high-efficiency, activated carbon, etc., and different types of filters have different filtration effects on different pollutants. You should choose the type of filter that is suitable for your home environment.

3. Noise: The noise of the air purifier is also a factor to consider. You should choose an air purifier with low noise and low operating noise to ensure the comfort of the home.

4. Energy consumption: The energy consumption of the air purifier is also a factor to consider. You should choose a spring air purifier with high energy efficiency to save energy and reduce the cost of use.

5. Brand reputation: The reputation of the air purifier brand is another indicator of choice. You should choose a brand with high credibility and good after-sales service to ensure product quality and after-sales service.
