Humans spend 90% of their time inside their homes. Inevitably, even more during these past three years due to the COVID-19 pandemic.
Based on a World Health Organization (WHO) report, more individuals die from indoor air pollution than outside. In addition, the air quality indoors was also found to be considerably more dangerous than outdoors.
As the health risk continues to grow, innovations are being continually developed to improve the quality of life. Appliances such as the best HEPA air purifier are creative and efficient solutions to these problems.
Air purifiers suited with High-Efficiency Particulate Air (HEPA) filters can help remove particles measuring up to 0.3 microns (µm). Pet dander, pollen, dust mites, mold spores, and tobacco smoke are allergens that can cause asthma. These gadgets get rid of these foreign materials by filtering them out of your room’s air.
Ensuring that the air you and your family inhales is clean and free from contaminants is vital for every home environment. Below are some must-haves for the air purifier that you would choose to purchase:
Be CADR or MERV Guided
Clean Air Delivery Rate (CADR) measures a purifier’s capacity to clean the air. The larger the room you need to use the air purifier, the higher the CADR score you will need to look out for in a device.
In general, the CADR score should equate to two-thirds of the room area where you will place it. Ideally, an air purifier that scores at least 300 would be best for most users.
Accordingly, small-sized air purifiers are best for personal usage of up to 299 ft2. Rooms measuring 699 ft2 will benefit medium-sized devices. Large ones can accommodate rooms up to 1,900 ft2. Lastly, some models can filter your whole house!
While CADR is a rating tool ideal for residential air purifier use, industrial ones are often measured using Minimum Efficiency Reporting Values (MERV). It is an indication of the device’s filtration power. The ratings can be from 1 up to 16, yet a value of 8 or above is the most ideal.
Take Note of the ACH
Consumers who choose the best HEPA air purifier also purchase it for its capacity to minimize asthma and allergies. HEPA filters can aid in preventing symptoms of these illnesses by trapping the immune triggers.
The device’s air change per hour (ACH) rate pertains to how many times the purifier can completely filter the designated area in an hour. Generally, it would be best to acquire a device that can clean the air volume in its space up to four times in an hour. Its efficiency ensures the cleanliness of the surroundings and the prevention of allergen accumulation.
Stay Away from Ozone Generators
Ozone is naturally produced after some air purification processes are done. However, this gas can cause damage and irritation to the lungs. Even inhaling low amounts of this gas can cause coughing, throat irritation, chest pain, and shortness of breath.
Although ozone is used for air sanitation in inhabited rooms, you shouldn’t undermine its role as a pollutant when inhaled. Thus, it is better to refrain from using these ozone generators in confined spaces such as your home.
Look for Verification
The Association of Home Appliance Manufacturers (AHAM) group has its standards and verification process for home appliances. It is voluntary for manufacturers, but it provides additional proof of its effectiveness and usability. This certification also issues the CADR rating and room size guidelines beneficial to consumers.
