What are the characteristics of household air purification equipment, and how to choose air purifica

Anhui people and analysis of air purification equipment have two necessary hard indicators: 1. It is necessary to ensure that the indoor air reaches a certain number of air changes. 2. The primary purification efficiency of air purification equipment must be relatively high.

If there are continuous sources of pollution in the room, these two hard indicators of air purification equipment can keep the indoor pollutants at a lower concentration.

Professional air purifier dealers tell you that air purifiers are useful, but you have to be able to choose and choose the right one. Negative ions have a single function, which is basically useless. In addition, it depends on the HEPA filter, the larger the area of this net, the better the filtration effect; To remove odor and formaldehyde, it depends on the activated carbon filter, the same amount, area and performance are related.

Small size, especially the small area of the filter screen, thin thickness, the performance is relatively poor, the general weight is about 5 kg, the power is less than 40w, the amount of activated carbon does not exceed 100 grams, ** within 1,000 yuan; High-end products are equipped with photocatalytic nets, of course, you have to really see this net, some out of nothing, ten purification, nine purification or something, not counting. Data control, you can pay attention to the CADR value, as well as the authoritative report of formaldehyde removal rate, the value is large, the purification is fast, and the performance is naturally good. It's useless to just listen to the seller's introduction to the purification area, because there is no standard for this, so you can talk nonsense.

A reliable seller will definitely provide a report on CADR value and formaldehyde removal rate. Just buy it according to it, a little simpler, according to the CADR value, 1 cubic meter is about 10 yuan. Whether it's great value or not, it's clear.

Of course, you have to pay attention to the formaldehyde removal rate at the same time. Having said so much, I directly recommend: the Aier iair868C model produced by Shanghai Lavida Environmental Protection.

The authoritative measured CADR value is 441 cubic meters, and the aldehyde removal rate is 97% in 2 hours. The measured value of the air outlet is less than 5ug m 3Even the CADR value of the 8,000-piece Abdul Lane purifier is slightly lower (425 cubic meters per hour).

1 is to see the applicable area, 2 is to see the minimum net particles, 3 is to see the air volume.

Air purifiers have become common household appliances, what should I pay attention to when buying an air purifier? When purchasing an air purifier, you should carefully observe whether there is a company name, product name, product manual, implementation standards, certification marks, consultations, etc. Consider the lifespan of your air purifier.

Consider the purifying capacity of your air purifier. If you have a large space, choose an air purifier with a large amount of clean air.

When purchasing an air purifier, you should carefully observe whether there is a company name, product name, product manual, implementation standards, certification marks, consultations, etc. are clearly marked on the outer packaging of the product. Generally, as long as it is a product produced by a regular manufacturer, these details will generally be clearly marked.

If not, it means that the product is produced by a small manufacturer, and it is not recommended for everyone to buy it. When buying an air purifier, you should also carefully observe whether the product instruction manual clearly indicates the specific operation steps, operation precautions, filter replacement operation, etc. If this information is incomplete, it can easily cause problems for users when using the air purifier.

At the same time, consider the purification capacity of the air purifier. If you have a large space, choose an air purifier with a large amount of clean air. In general, larger air purifiers have more purification power and are also more noisy.

Consider the lifespan of your air purifier. Air purifiers require frequent maintenance during use, and the key parameter that affects the service life of an air purifier is the cumulative purification volume. Depending on the type of air purifier, the air purifier's filter element needs to be replaced or cleaned regularly.

At present, electrostatic air purifiers need to clean the filter element regularly, and other purifiers generally need to replace the filter. When purchasing a purifier, pay attention to the nominal cumulative purification volume. The greater the amount of purification accumulated, the longer the life of the air purifier will be.

Choose products with pre-sales and after-sales guarantees. Whether buying products online or offline, consumers should buy them through formal channels. Don't blindly believe in channels such as transmission, sales, and membership, and avoid buying fake and shoddy products.

At the same time, as a high-consumable product, the after-sales service of air purifiers is particularly important. Some air purifiers sold through third-party platforms or dealers have a short warranty period and defective follow-up repair services, which greatly shortens the service life of the product. Therefore, when buying an air purifier, consumers should carefully understand the after-sales service, warranty terms and restrictions of the product to avoid unnecessary troubles in the after-sales process.

In addition, after purchasing a product, consumers must keep invoices and other shopping vouchers for future rights protection.

When buying an air purifier, you must pay attention to choosing some air purifiers with quality assurance and good reputation, and also pay attention to its appearance, as far as possible to ensure that it is smooth and glossy.

If you want to go to a regular place to buy, you have to buy one with very good quality, more functions, very high-tech, very convenient to use, and one with after-sales and a very favorable price.

Now air purifier is a very common home appliance, when choosing an air purifier, the first thing to choose is the brand of a large company, because the quality is guaranteed.

1. The main functions of MIA air purifier are:

1. It can remove dust, particles, dust and other substances in the air to prevent the human body from inhaling into the body.

2. It can remove formaldehyde, benzene, pesticides and other toxic substances in the air to prevent physical discomfort caused by human contact.

3. It can remove the strange smell of tobacco and oil smoke in the air, ensuring the freshness of indoor air and making people feel refreshed.

Second, there are a few points that should be considered when choosing an air purifier:

1. Attention should be paid to the performance characteristics of the product. When purchasing an air purifier, you should check the nominal clean air volume, cumulative purification volume, purification energy efficiency and noise of the air purifier, from which you can see what kind of pollutants the air purifier has and how good the purification ability is.

2. You should consider your own use environment and the effect you want to achieve. For newly renovated houses, the most important thing to remove is formaldehyde, toluene and other gaseous pollutants, at this time, we should pay attention to the purification effect of the product for gaseous pollutants, and give priority to the purchase of products that are clearly marked with formaldehyde clean air volume and formaldehyde cumulative purification amount. For places that deal with haze weather, you should give priority to the amount of clean air and the cumulative purification of particulate matter of the product, and choose an air purifier that suits your needs.

3. At the same time, the purification capacity of the air purifier should be considered. If the space is larger, you should choose an air purifier with a large amount of clean air, generally speaking, a larger air purifier has a stronger purification capacity and the more noise. When choosing a purifier, you can refer to the applicable area or clean air volume marked on the air purifier manual or nameplate, and the relationship between the two is about:

Usable area = particulate matter.

4. Consider the service life of the air purifier. Air purifiers require frequent maintenance during use, and the key parameter that affects the service life of air purifiers is the cumulative purification volume. Depending on the type of air purifier, the air purifier needs to be replaced or cleaned regularly.

At present, electrostatic air purifiers need to clean the filter element regularly, and other purifiers generally need to replace the filter.

5. When purchasing an air purifier, you also need to pay attention to the purification energy efficiency and noise of the air purifier. For purifiers with the same amount of clean air, the higher the purification energy efficiency, the more electricity saving. Since the air purifier is a place where people work and live for a long time, special attention should be paid to the noise of the air purifier, and the noise of the purifier can be checked on the nameplate or the noise on the manual.

Generally speaking, the greater the amount of clean air, the greater the noise of the air purifier, the current air purifier noise is generally 45 70db(a), and it is necessary to pay attention to whether the product is wrongly labeled when encountering a particularly small nominal product.

Do air purifiers work.

The air purifier has a certain purifying effect on air impurities, but it does not have the ability to completely purify, because it cannot circulate the air of the whole set of living rooms, such as two bedrooms and one living room, and can only circulate the air of one space for purification.

For example, when someone passes by, they will feel the wind caused by the movement of air, but if two people are far away, they will not feel the wind.

Air purifiers can only make local air flow, so they can only be partially purified. Therefore, air impurities such as micron and above particulate matter (such as decoration pollutants such as formaldehyde) in the air cannot be completely removed.

So within the range that can be purified by the air purifier, can the air impurities be solved? Air purifiers can address microns and above particulate matter in the air, but they can't address the renovation pollutants in the air.

The direct reason is that the purification speed of most air purifiers is less than the volatilization rate of the decoration pollution source, and the fundamental reason is that the air purifier does not solve the volatilization source of gaseous decoration pollutants.

Do air purifiers work.

Formaldehyde will be produced after the decoration of all new houses, many users know that the newly renovated house can not be moved in immediately, must be ventilated for a long time to move in, if you want to live in the new house in a short time, in fact, at this time you can consider putting an air purifier in the newly renovated house, so that the formaldehyde in the new house These harmful gases can be cleaned quickly.

In fact, many people now have certain questions about whether the air purifier is useful, the air purifier is mainly composed of a motor, a fan, an air filter, these systems, when working, the motor and fan in the machine will make the indoor air flow, then the polluted air will be sucked into the machine, and the air filter in the machine will remove various polluted areas in the air. Nowadays, there are many new types of air purifiers that will add a negative ion generator to its air outlet when in use, which can continuously ionize the air, and eventually produce a large number of negative ions, and then send it out of the machine through the fan to finally clean and purify the air.

The general expiration date of an air purifier is about 12 months, which is a year, but the expiration date after opening is greatly reduced to about 3 to 6 months. The air purifier with the activated carbon adsorption function in the air purifier is very effective in a short period of time, but the cost will be high if it is used for a long time because the activated carbon inside needs to be replaced every 2 months or so. Therefore, when choosing an air purifier, you should consider what kind of air purifier your family needs, and which one is more cost-effective.

Indoor air quality standards.

Standard indoor air means that it is the most suitable environment for human settlements, simply put, the indoor air is non-toxic, odorless, colorless, noise-free, and abnormal. The main components of the air include oxygen, formaldehyde, water vapor, particulate matter, etc., and indoor air quality can be detected through professional pollution detection tools.

Once the indoor air quality is polluted, it can be identified from the color, smell and sound, and the corresponding indoor air pollution control plan and measures should be taken immediately.

Indoor air pollution control program.

1. Ventilation method.

It is used for the decoration of the room with light odor, good ventilation conditions, and long-term ventilation. For the living room with heavy socks pollution and poor ventilation conditions, it is difficult to achieve the effect of removing odors.

2. Plant law.

Placing green plants such as spider plant and aloe vera in the living room, some plants have the effect of absorbing harmful gases, and also have the effect of beautifying the living room, but the onset time is slow.

3. Fragrance method.

Use air aromatics, sachets of aromatic plants, tea, pineapples, etc. to combat indoor air odors. However, air aromatics and bagged aromatic plants basically play a covering role or a psychological effect at all, and cannot play a fundamental role in eliminating the pollution of rubber inducing.

4. Active carbon adsorption method.

The principle of activated carbon adsorption and purification is used to adsorb macromolecular gas suspended particles in the air, and the purpose of filtering and purifying the air is achieved by forcing air circulation. The best active carbon adsorption method at present has an air purification system.

5. Chemical method.

The so-called chemical method is to use the principle of chemical decomposition reaction, and there are many formaldehyde scavengers on the market to remove odors. This method is more suitable for the treatment of materials such as plates in the decoration process, so as to prevent decoration pollution.

First of all, the environment in which it will be used and the effect to be achieved should be considered. If the indoor soot pollution is heavy, you can choose to buy an air purifier equipped with HEPA air filtration material and catalytic activated carbon. HEPA high-density filter material is one of the most advanced air filtration materials in the field of indoor air purification, which can well filter and adsorb pollutants above microns, and it has a strong purification ability for smoke, inhalable particles, bacteria and viruses.

Catalytic activated carbon has a better purification effect on odors and harmful gases. If the room has just been renovated and formaldehyde needs to be removed, you should buy a purifier that removes decoration pollution. In addition to removing formaldehyde, this type of purifier generally has the effect of removing smoke and dust, and even humidification, which is an all-round air purifier.

Secondly, the purification capacity of the air purifier should be considered. If the room is large, you should choose an air purifier with a large amount of air per unit time. Generally speaking, larger purifiers have more purification capacity, for example, a 30-square-meter room should choose a 120 cubic meter hour air purifier.

Shifu Bang home doctor suggests that you can refer to the introduction in the sample or manual to choose. Third, the service life of the purifier should be considered. Due to the increase of the use time of the purifier using the principle of filtration, adsorption and catalysis, the purification capacity of the equipment decreases, and the filter screen and filter cartridge need to be cleaned and replaced.

Fourth, the matching of the layout of the room and the purifier should be comprehensively considered. The design of the air purifier inlet and outlet air has a 360-degree annular design, and there are also one-way inlet and outlet air inlet and outlet. Since the layout of the room will affect the effect of purification, if you want to achieve arbitrariness in the placement of products, you should choose products with annular air inlet and outlet design.
