The Ultimate Guide to Choosing an Air Purifier: Tips for Clean Air in Your Home
Introduction: Why Air Purifiers Are Important
In an era where air pollution has become a major global problem, especially in Thailand which regularly faces PM2.5 dust and other pollutants, air purifiers are not just ordinary appliances. But it is an important device that helps protect your health and the health of your family members from the dangers of these air pollutants. Breathing in contaminated air over the long term can lead to serious health problems. Such as respiratory diseases, heart disease, and even cancer. Having an effective air purifier is an investment in long-term good health.
พื้นที่ห้อง (ตารางเมตร) x ความสูงของห้อง (เมตร) x 5 = CADR (ลูกบาศก์เมตรต่อชั่วโมง)
ตัวอย่าง: หากห้องของคุณมีขนาด 20 ตารางเมตร และมีความสูง 2.5 เมตร ค่า CADR ที่เหมาะสมคือ 20 x 2.5 x 5 = 250 ลูกบาศก์เมตรต่อชั่วโมง
จำนวนรอบการเปลี่ยนอากาศต่อชั่วโมง (ACH): นอกจากค่า CADR แล้ว อีกค่าหนึ่งที่ควรพิจารณาคือ ACH (Air Changes per Hour) ซึ่งหมายถึงจำนวนครั้งที่เครื่องฟอกอากาศสามารถกรองอากาศทั้งหมดในห้องได้ภายในหนึ่งชั่วโมง โดยทั่วไปแล้ว ค่า ACH ที่เหมาะสมคือ 4-5 รอบต่อชั่วโมง
Key Factors to Consider When Choosing an Air Purifier
Room Size and Clean Air Delivery Rate (CADR)
Room Size: The first thing to consider is the size of the room where you want to use the air purifier. Each air purifier model has a different air purification capacity. This is measured by the CADR (Clean Air Delivery Rate) value. The CADR value indicates the amount of clean air that the machine can produce per minute. Generally, The larger the room The more you need an air purifier with a higher CADR value.
Calculating the Appropriate CADR: There is a simple calculation formula. To find the CADR value that is suitable for your room size:
Room area (square meters) x room height (meters) x 5 = CADR (cubic meters per hour)
Example: If your room is 20 square meters and has a height of 2.5 meters, the appropriate CADR value is 20 x 2.5 x 5 = 250 cubic meters per hour.
Air Changes per Hour (ACH): In addition to the CADR value, another value to consider is ACH (Air Changes per Hour), which refers to the number of times an air purifier can filter all the air in a room within one hour. Generally, The appropriate ACH value is 4-5 cycles per hour.
Air filters are the heart of an air purifier. It traps various pollutants in the air. There are many types of air filters. Each type is effective in trapping different pollutants:
Pre-filter: Traps large particles such as dust, hair, and pet dander.
HEPA (High-Efficiency Particulate Air) filter: Traps particles as small as 0.3 microns, such as PM2.5 dust, pollen, allergens, mold, and some bacteria. Highly efficient HEPA filters can trap up to 99.97% of particles.
Activated Carbon filter: Absorbs unpleasant odors, chemicals, and toxic gases such as formaldehyde, benzene, and volatile organic compounds (VOCs).
Other filters: Some models may have additional filters, such as Photocatalytic Oxidation (PCO) filters that use UV light in conjunction with a catalyst to break down pollutants. Or an ionizer filter that releases negative ions to trap particles in the air.
Choosing the Right Filter: Depends on your needs and the pollution problems you want to solve. If you are concerned about PM2.5 dust and allergens, a HEPA filter is essential. If you want to get rid of unpleasant odors and chemicals You should choose a machine with an Activated Carbon filter.
Some air purifiers can be noisy while operating. Especially when turned on with high fan power. If you plan to use an air purifier in your bedroom or office. You should choose a model with a low noise level. Generally, A noise level below 50 decibels (dB) is considered quiet.
The price of air purifiers varies. Depending on the brand, model, function and technology You should compare the prices and features of several air purifiers before making a purchase decision. Additionally, You should also check the warranty period and after-sales service of the manufacturer or distributor.
Check that the power plug is plugged in and the machine switch is turned on. Check that the filter is installed correctly and is not too dirty. If it still doesn't work May be caused by technical problems. You should contact the service center.
Check if any foreign objects are stuck in the machine. Clean the filter and air vents. If it's still loud May be caused by damage to the motor or internal parts. You should contact the service center.
Air purifiers with HEPA filters can trap allergens such as dust mites, pollen, and pet dander. Effectively Helps reduce nasal congestion, runny nose, sneezing, and coughing.
Air purifiers help reduce the risk of respiratory infections.
Air purifiers can trap germs such as bacteria and viruses. that floats in the air Helps reduce the risk of respiratory infections. Especially during disease outbreaks
