The ways to buy an air purifier help reduce dust and eliminate germs in the house
What is an air quality purifier and how is it useful? How to buy it? Let’s take a look at the working principle of an air purifier, advantages and disadvantages before making a purchase. It is undeniable that today the air around us is very polluted which is not only on the streets But our homes are still full of air pollution that causes allergies whether it is dust, bacteria, viruses, and contaminants that come from the air. If today you are going to find a helper to get rid of these things, such as an air purifier for use in the house, today’s jar dot com has information on air purifiers for you to consider before making a purchase to know if an air purifier is really necessary for us or not?
What is an air purifier?
Air purifiers (Air Purifier or Air Cleaner) are electrical appliances that help eliminate foreign objects in the air such as dust, bacteria, viruses, the cause of allergies, including unpleasant odors. The smell of cigarette smoke, musty smell, bad smell in the house disappeared. The air purifier works by sucking air into the device through a filter to trap them and let out fresh air instead.
Air purifier system
Even now, the air purifier has added many functions. But can divide the operation system of the air purifier into 5 main systems according to the function as follows
- Air filters
Air Filter or air filter the system captures dust, bacteria, viruses, or allergens. There are types made of paper, fibers, and mesh, but the most commonly used type today is a HEPA air filter or High-Efficiency Particulate Air, a type of filter made from fiberglass fibers. It is designed to capture particles as small as 0.3 microns and has an effective capture efficiency of not less than 99.97%. The average lifespan is 3-5 years.
- Electrostatic Precipitator
Electrostatic Precipitator Air filtration system that operates using electrostatic principles by releasing a negative electric charge to collect dust or small particles that are positively charged into a group to make more weight and fall to the ground not floating in the air
- Gas-phase air filters
Gas-phase air filters a system for eliminating odors works by using chemicals such as activated carbon, also known as activated carbon, to absorb odors various undesirable and toxic gases away
- Ozone generator
Ozone generator A system that uses UV light or electricity to generate ozone. To kill germs, chemicals, as well as to eliminate odors mixed in the air to disintegrate and make the air clean again
- UV Light
UV Light is a system that uses ultraviolet rays to eliminate germs such as bacteria, viruses, fungi, or other substances in the air that are harmful to health.
Purchasing an Air Purifier
- Room size
Choose the size of the air purifier to suit the room or area to be installed because each air purifier is effective in covering different areas. For example, if we buy a small air purifier but put it in a large room It will cause the air purifier to not work at full efficiency. But if a large air purifier is placed in a small room, it will waste energy. Importantly, the room where the air purifier is installed should be a closed room. To help prevent dust from entering continuously Make the machine work efficiently enough.
- Operation system
Another important thing to look at before buying an air purifier is the operating system whether it has the features that meet the needs and meet our usage needs or not focusing mainly on the type of filter or filter. Should choose an air purifier with HEPA filter (HEPA filter), which helps filter small dust well and trap a lot of dust. This includes the need for additional functions that go beyond air filtration or deodorization, such as air quality sensors, filter replacement indicators, and speed controls and remote command. It is a feature that we should consider as well. Because it is the part that affects each device, each brand has a different price.
- Airflow value
Airflow value or wind speed meter from the amount of air being sucked in and the time it takes to release the air from the air purifier. If the air purifier has a high Airflow value, it means that air purifiers are effective in purifying the air quickly.
- CADR value
CADR (Clean Air Delivery Rate) or fresh air generation rate per minute is a universal value used to measure the performance of an air purifier. The higher the CADR value, the better the performance of the air purifier.
The noise level of the air purifier is another factor that should not be overlooked. A good air purifier should have a low noise level while it’s working to prevent disturbances while resting the optimum sound level should not exceed 30-31 decibels.
- Energy saving
Will the air purifier consume electricity or not? Partly depends on the filter. If the filter is very dense with little air permeability it will make the appliances a lot. Therefore, choose a filter that has good airflow to reduce the use of electricity at work. You can also compare the electricity bill from the energy-saving label 5 from many models to make a decision.
It’s not just the price of the indoor air quality purifier. But we must also consider the cost of replacing filters or air purifier filters. This is because all air purifiers require replacement filters or filters regularly. To help various systems to work efficiently, Therefore, before buying an air purifier, it is important to look at the price of the filter and other maintenance.
For the principle of buying an air purifier to help eliminate PM2.5 dust, notice the filter. It was found that the filter High-Efficiency Particulate Air Filter (HEP) is the most suitable and popular type. Because it is efficient, cost-effective, and has a filtration rate of H13 (or higher), however, it must be considered in conjunction with the amount of fresh air generated (CARD), airflow efficiency (airflow), and the size of the room space. To help facilitate the fastest, most, best, and most efficient dust reduction.
- Helps reduce the incidence of allergies caused by dust, pollen, or animal fur.
- Helps to inhibit the growth and eliminate bacteria, germs, and fungi.
- Help turn polluted air into the fresh air and free from unpleasant odors
- Does not make the dust disappear from the whole house Therefore; the house should be cleaned at the same time.
- Air purifiers do not cure allergies because the air purifier can only absorb dust or allergens in the air.
- Not every air purifier can eliminate odors should choose one that has an activated carbon filter layer as well.
