In fact, there is no such thing as a pet-grade air purifier. However, there are air purifiers suitable for capturing air pollutants brought by pets.
The air pollution caused by pets mainly includes hair, dander, ticks, bacteria, and odor. The hair can be large or small, as large as tens of millimeters, or as small as tens of micrometers. The large ones can move around with the airflow, and the small hairs can be suspended in the air for a long time and are easily inhaled by people, causing a burden on the respiratory system; The size of crumbs ranges from micrometers to millimeters, which can easily carry allergens and bacteria, causing human allergies and bacterial infections; the size of ticks range from 0.1 millimeters to several millimeters, and their emissions can float in the air, contact or be inhaled The human body can cause allergies; the size of the bacteria brought by pets is in the micron level, and the main distribution range is 0.5-1.0 microns. The bacteria can float in the air independently or with the emissions of flying dust, hair, dander, mites, etc. In the air; pets breathe or excrete will bring some peculiar smells or odors, these peculiar smells include ammonia, hydrogen sulfide, uric acid and so on.

After understanding the pollutants that pets may bring, let's talk about how to choose an air purifier for families with pets. Mainly consider the following 4 aspects, consumers can make choices according to the actual situation of their pets.
- The direction of the air in and out of the air purifier. The air purifier should be able to catch the fluff of pets scattered in the air or the hair on the ground near the air purifier in time. From the perspective of the air inlet and outlet directions of the air purifier, it is not a good choice for the rear side to enter the air before the air exits, because the front air sweeps the ground and raises the ground pollutants (dust, hair, etc.), which is easy to be affected. People inhale. I suggest to use an air purifier with lower air inlets and left and right air inlets (a few tens of centimeters above the ground) at the same time. The air outlet can inhale pollutants suspended in the air, and the upper air outlet can ensure that the clean air is directly delivered to the breathing parts of the person.
- Pre-filter or pre-filter The air purifier should have a pre-filter that is convenient for trapping hair. This filter is mainly used to collect hair and larger particles, has a larger dust holding capacity, and is easy to clean (preferably washable). Without this layer of net (similar to the filter used in the internal air conditioner), these hairs or large particles will be adsorbed on the main filter (filter). When the machine is turned off, because there is no suction, the pollutants will easily escape from the filter. , Floating in the air again; at the same time, these larger particles or hair will increase the burden of the utra HEPA air purifier and reduce its service life.
- The filtration efficiency of air purifiers against PM2.5. Because pets can easily carry and produce bacteria as small as 0.1 micrometers, ordinary air purifiers have very low filtration efficiency for such extremely fine particles, while high-efficiency air purifiers, namely The H12 or H13 air purifier can remove 99.5% (H12) or 99.97% (H13) particles as small as 0.3 microns (bacterial grade) at one time, thereby reducing the time and quantity of fine particles such as bacteria. Protect health.
- The ability of the air purifier to handle peculiar smells For the peculiar smell or odor produced by pets, in addition to ventilation, it is also a good choice to use an air purifier with strong deodorizing ability. Practice has proved that activated carbon can absorb a variety of odors and harmful gases. When choosing a deodorizing air purifier, two aspects are mainly considered: A) The efficiency of removing gaseous pollutants. In view of the air purification national standard, ammonia, etc. (pets produced Odor) Included in the test items, I suggest consumers refer to the removal efficiency of formaldehyde.How much does the filter contain activated carbon or other deodorizing materials Generally speaking, for the same type of activated carbon, the greater the amount of carbon in the filter, the greater the content of activated carbon More, the longer its life span. The former indicator represents the speed of odor removal, and the latter indicator represents the service life of the filter.
How to determine the number of air purifiers to use After knowing how to choose an air purifier suitable for use in a pet family environment, let's talk about the number of air purifiers used. Many businesses advertise that an air purifier can cover 80 square meters and is suitable for use in the whole house. In fact, the applicable area of the air purifier is only a theoretical value. In actual use, due to the limitation of the house structure (wall blocking, door opening and closing), the air circulation capacity of the air purifier and other factors,
As a result,air purifier for large room often achieve the desired purification effect when used in large spaces,but other small air purifiers can not. In order to achieve a better use effect, I suggest that each independent space (that is, each room) is equipped with an air purifier of a suitable size. The specific configuration method can select the appropriate air purifier according to the volume of the room and the required number of air changes. For example, a room with a 3m floor height of 16 square meters has a volume of about 48m³. It is calculated based on 3 to 6 air changes per hour. An air purifier with a CADR value of 144-288m³/h is sufficient. You can choose a larger value when the pollution is serious or you need to quickly treat the pollutants, and you can choose a smaller value when the pollution is lighter.
Choosing an air purifier must first meet the functional needs. I think there are at least 3 benefits of arranging air purifiers at multiple points: 1) It is conducive to the proximity of the air purifier to the pollution source, which can remove the pollutants in a timely manner and avoid the spread of the pollutants; 2) It is conducive to choose air purifiers with different functions according to different pollutants, which is more targeted; 3) It is conducive to energy saving. In a room with no people moving, you can close the door and close the air purifier in the room.
