9 Recommended Air Purifiers | Home Appliance Professionals Explain How to Choose and Features of Popular Manufacturers

"Dirty air collects underneath. If you have a baby who goes high and high, you should suck dust and pollen with an air purifier . Even if you think that the room is not so dirty, the filter will be used for half a year. It can be pitch black. "

How to choose an air purifier

When choosing an air purifier, there are five points: "presence / absence of humidification function", "applicable floor area", "filter", "ease of maintenance", and "function" .

1. Presence or absence of humidification function

2. Applicable floor area: More than twice the size of the room. If you want to prevent pollen and tobacco, use more than three times as much.

3. Filter: With a deodorizing filter to prevent odors from pets and cigarettes. Check the replacement life as it depends on the product.

4. Ease of maintenance: For those who have trouble cleaning, consider products that automatically clean the pre-filter or products that can be cleaned simply by replacing the filter.

5. Function: It is convenient because you can see the air environment of the room at a glance if you can link it with your smartphone.

Presence or absence of humidification function

Some air purifiers have a humidifying function. It is convenient because you can use both the functions of a humidifier and an air purifier with one unit.

"Among the air purifiers, the humidified air purifier is especially popular. The advantage is that one unit can use two functions and does not take up space. The internal structure becomes complicated and it is difficult to maintain. , There is a demerit that the power is weak .

Humidified air purifiers are popular in Japan due to housing conditions, but there are only a few products overseas. I use them separately. "

Applicable floor area

The applicable floor area represents "the size of a room that can purify particles and gas contained in the smoke of five cigarettes in 30 minutes." The wider the applicable floor area, the faster the air can be cleaned.

" The most important thing when choosing an air purifier is the applicable floor area . If you put a small one that does not fit the room, you may not be able to feel the effect because the dirty air cannot be removed to every corner of the room.

It is important to select an applicable floor area that is more than double the size of the room to prevent dust and house dust . Choose more than three times as much pollen and tobacco measures . Air purifiers don't work on things that fall, so you need to suck them powerfully and quickly before particles such as pollen fall. "

filter

The air purifier has a structure in which large dust and dirt are removed with a pre-filter, and fine dust that has passed through it is removed with a HEPA filter (dust collection filter).

The HEPA filter needs to be replaced in a few years because dirty substances accumulate and its performance deteriorates. The number of filters installed and the life of the filters vary depending on the product. Please choose it in consideration of the time and effort of maintenance.

▼ Main filter types

" The frequency of filter replacement varies from manufacturer to manufacturer, so check it out. If you are concerned about the smell of pets or cigarettes, choose one with a deodorizing filter . TAFU filters are expensive, but they are strong against water and oil and last a long time. "

Easy to clean

If care is not taken, the filter will easily wear out, which may increase running costs.

"Dust that collects on the pre-filter needs to be vacuumed at intervals of about two weeks. For those who are troublesome, we recommend a product with a function that automatically cleans it .

The Blue Air air purifier does not require cleaning the filter, and it is OK if the HEPA filter is replaced in about half a year to a year . It's easy to clean, but HEPA filters cost around 7,000 to 15,000 yen. Recommended for those who want to reduce the maintenance effort even if running costs are high. "

The image of product care is described in "Guidelines for caring for each product and parts replacement" at the end of the sentence.

function

"If you have a smartphone interlocking function, the price of the main unit will be a little higher, but it is convenient . Even if you use an air purifier, it is difficult to realize the effect because you can not see the air, and some people stop using it. Once you know how dirty it is, it's easy to continue using.

With a dust sensor, it is easy because it automatically adjusts the strength , such as powerful suction when grilling meat. For those who are concerned about the sound when using it in the bedroom, we recommend products with a silent mode . "

Features of popular manufacturers

" Daikin and Panasonic are for people who have a high price and are highly aware of the air environment .

Sharp has an excellent balance between performance and price . The main unit price of Iris Ohyama is cheap .

Hitachi has many products with specifications that are easy to clean . There are products that can be removed by washing the odor of the deodorizing filter with lukewarm water, and products with a pre-filter automatic cleaning function.

Blue Air has a high main unit price and running cost, but it is attractive that it requires less maintenance . Some products have a fashionable design and do not deteriorate in shape even after many years of use.

Dyson has a structure that makes it difficult for gaps to form when the HEPA filter is fitted, and it is a specification that makes it difficult for dirty air to come out . Since the applicable floor area is small, it is more suitable for private rooms such as bedrooms than large places. "

"Air purifiers that are cheaper are less durable and tend to be fragile. Also, there are many noisy air purifiers and it can be difficult to fit the filter. Some of them are worried about safety. "
