Is there an air purifier that doesn t require consumables now?

The purifier without consumables can only purify larger particles, and the effect is not very good.

After all, the pollution is not sucked by itself or the air purifier is sucked, it must still be the body is important, and the consumables are not very expensive to change once or twice a year, the key is that it is useful, and then the Forest air purifier is used, the effect is much better, and the gas pollution can also be purified, and it can also be sterilized and disinfected.

It depends on what pollution source you need to purify, the principle of an air purifier is to use a filter to filter air impurities and use negative ions to purify bacteria.

The air purifier without consumables is actually a negative ion generator, which can evolve the bacteria in the air very well, but it is not strong for the impurities in the air (he can't effectively collect pollution, and your machine will produce 2 times of pollution as soon as it is turned off), and it is even more powerless for formaldehyde and haze (not enough power). and produce a certain amount of ozone pollution. (A small amount of ozone can still be sterilized, but if there is more, there will be problems, which is why he does not dare to make the power bigger.)

The main disadvantage of consumables is the high cost of purification, and you have to buy a filter. However, it should be noted that the filter for purifying formaldehyde is not the same as the filter for purifying haze. In fact, the evolution of formaldehyde and smog is not ideal.

Because of the volume, the consumables purifier is generally equipped with a small ionizer, and it will have the function of no consumables.

The air evolutionary device is divided into consumables and non-consumables, that is, the mode of action is different, and the consumables are used by the media filtration type, which can filter particles that can enter the lungs with a diameter of microns. It needs to be replaced regularly, otherwise the filter will be clogged.

The other is that there is no need for consumables, electrostatic dust collector, there is a high-voltage negative electrostatic field on the machine, which can adsorb the dust in the air, which does not need to replace the consumables, and only needs to clean up the adsorbed dust regularly.

These two methods have their own advantages and disadvantages, the electrostatic type is silent but the efficiency is lower, and the filter type is very efficient because there is a fan to actively supply air, but the noise will definitely be there, and the consumables also need to be replaced frequently.

As for which one is suitable for you, it depends on the environment you are using, whether it needs to be purified quickly, or what requirements are there for time and air cleanliness.

At present, the purification methods of air purifiers on the market can be roughly divided into two types: one is the traditional HEPA filter air purification (with consumables), and the other is the negative ion air purifier (without consumables).

The purification method of the filter air purifier is a passive purification in which the fan rotates, the polluted air is pumped into the machine, and then filtered by the filter. The advantage of this type of purification method is that it has a better purification effect on large particulate matter. The disadvantage is that with the increase of use time, the amount of pollutants adsorbed on the filter will also increase, and it is necessary to replace the new filter every few months, which is more expensive for long-term use.

Moreover, the rotation of the fan will inevitably produce the problem of high noise and high power.

The anion air purifier uses the characteristics of high activity and strong diffusion of eco-grade anion to quickly diffuse the released negative ions, capture the particulate pollutants in the air, and then make the particulate pollutants condense and settle. The advantage is that negative ions can diffuse into all corners of life, fully purify, clean without dead ends; And for the smaller the particle size of the contaminant, the better the purification effect; It also solves the problem of replacing consumables, noise, and power for filter air purifiers. The disadvantage is that there are few artificial anion generation technologies that can generate high activity and strong diffusion, and most machines still generate large particle size anion ions with low concentration and difficult to diffuse.

Professor Tao Mingzhang, chief researcher of the Chinese Air Anion and Ozone Research Society, made it clear that at present, the artificial anion generation technology is more advanced only eco-grade anion generation chip technology and nanofullerene anion release technology, and the senpepti-based anion air purifier using this technology realizes ultra-quiet, zero consumables, and ultra-fine purification, with a power of only 2 watts, and can be used 24 hours a day for 365 days, with a life span of up to 200,000 hours.

The consumables without consumables are oxidized by ozone, or treated by photocatalysts, and those with consumables are generally adsorbed by activated carbon, and it is best to combine the two!

1. The purification principle of the air purifier with consumables mainly relies on filtration adsorption, and the filter type air purifier relies on layers of filters to filter and block dust, and more than 90% of the air purifiers in China use the filter to remove dust. However, the adsorption effect of filter air purifiers on fine dust that is harmful to the body or even smaller is limited.

2. The non-consumable air purifier with electrostatic integration mainly relies on the formation of an electric field at high voltage for adsorption and sterilization, and it will not favor one over the other for pollutants. This kind of purifier usually uses ESP electrostatic dust collection technology, which generates a corona by adhering to the tungsten wire with high voltage, releasing a large amount of positive charge, which collides with pollutants in the air to make it positively charged. The dust collection plate of the product has negative electricity, and the pollutants with positive charge move towards the dust collection board, and the pollutants with positive and negative charges offset each other after encountering the dust collection plate with negative electricity, and the pollutants are adsorbed on the dust collection board to release fresh air.

However, the filter must be replaced frequently.

2. 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.

3. Air purifier refers to products that can adsorb, decompose or transform various air pollutants and effectively improve air cleanliness. It is used in the home, medical and industrial fields, and the home field is divided into two categories: systematic fresh air system (divided into two sub-categories of heat exchange and no heat exchange) and stand-alone machine, which mainly solves the problem of indoor, underground space and car air pollution caused by decoration or other reasons. Due to the persistent and uncertain nature of the release of air pollutants in relatively enclosed spaces, the use of air purifiers to purify indoor air is one of the internationally recognized ways to improve indoor air quality.

4. The relevant standards of the national "Air Purifier" define an air purifier as "a device that separates and removes one or more pollutants from the air." A device that has a certain ability to remove pollutants in the air. It mainly refers to the single air purifier used in the room and the modular air purifier in the centralized air conditioning ventilation system.

In fact, now air purifiers have their own strengths and targets, and appearance is one thing, rational shopping.

The purchase of air purifiers is generally selected according to the CADR value, which is the amount of clean air in cubic meters per hour. For example, the CADR value is 300m3 h, and the general default floor height is meters, assuming that the home is 3 meters high, the area can be 300 3 1 = 100 square meters based on 1 air change per hour (average).

But there are a few things to keep in mind when using an air purifier:

1. The air purifier is useful, mainly for indoor air circulation filtration, which can only be said to treat the symptoms but not the root cause.

2. It may cause indoor secondary pollution. Some of the filters have activated carbon for physical adsorption and some chemical decomposition of formaldehyde removal, which may cause secondary pollution. For example, activated carbon adsorbs formaldehyde molecules and odor molecules, etc., which need to be replaced in time, otherwise these polluting molecules may be released after a long time (non-technical term, that's what it means).

3. If you use an air purifier, first of all, on the basis of abiding by the time of replacing the filter, see if you want to replace the filter in advance according to your indoor situation to avoid secondary pollution; Second, it is best to use the air purifier with doors and windows closed, otherwise it will reduce the purification effect; Thirdly, the purifier is mainly based on the CADR value to judge the applicable area, and based on the above, the purifier is mainly used in stages, or as an auxiliary product of Shenghuan fresh fan for indoor air treatment.

Summary: But if you really want to solve the indoor air problem, it is recommended that you consider installing Shenghuan fresh air. Wall-mounted fresh air fans, cabinet fresh fans and fresh air systems can be installed before or after decoration.

The function of the new fan is ventilation and filtration, with low energy consumption, and it can be used 24 hours x 365 days, which is the source purification compared with air purifiers.

At present, there are still a lot of air purifiers without consumables on the market, such as Langfeng air purifiers, Bruyard, etc., which are all consumables-free.

When the hunting module needs to be cleaned, the filter indicator flashes red for 2 minutes every 1 hour to remind you to clean the filter.

Before cleaning, we need to disconnect the power of the air purifier and let it stand for about 1 minute, this is to eliminate the residual static electricity inside the machine, and then we can take out the generating and collecting electrodes inside for cleaning. Use a special tool to collect brushes, if it is dirty, spray detergent, soak for 10 minutes, then brush repeatedly, and leave it in a ventilated place to dry.

If you are looking for a consumable-free air purifier, LightAir Air Purifier, I also just bought this air purifier, and it is really good to use this air purifier.
