Day in and day out, you probably don’t give much thought about the air you breathe, especially indoors. However, when you really think about it, the air inside your home is a lot more polluted than the air outside. And if you or someone in your family has allergies, then it’s critically important to make sure that the air in your home is as clean.
One way to be sure you are breathing clean air is by using an air purifier.
How do air purifiers work? What are HEPA air purifiers?
What Does HEPA Stand For?
HEPA stands for ‘high-efficiency particulate air’. The HEPA is an air filter that is integral to the function of an air purifier. In fact, many purifiers in demand nowadays are the ones equipped with a HEPA filter. HEPA filter for COVID is the most sought-after air purifier since the beginning of pandemic.
HEPA air purifiers remove miniscule airborne particles that serve as pathogens. Air purifiers of this type, like RENSAIR HEPA air purifier, help clean air particles as small as 0.3 microns. If these allergens are trapped and removed from the air, you will have a cleaner and healthier air.
How Does a HEPA Air Purifier Work?
HEPA air purifiers do have HEPA filters. HEPA air filters are specifically designed to trap pollen, pet dander, smoke, mould spores, dust and more. Similar to a net, HEPA air filters filter but do more than that. The surface of a HEPA air filter is more tightly knitted to bar even the microscopic particles harmful to health.
Living to its definition of being ‘high-efficient’, a HEPA air filter can capture common particles as small as the coronavirus. To illustrate this, HEPA filters remove airborne particles up to 99.97%. Though this doesn’t entail that those harmful particles are ‘destroyed’, they are trapped and entangled in between the fibres of the HEPA filter surface, making them too slow to escape and eventually die in the process.
At home, you may probably be exposed to pet hair and dander, smoke from your furnace or smoking household members, pollen grains, mould spores from walls (common on high-humidity areas) and bacteria and viruses that people transmit everyday. If you have a HEPA air purifier at home, you have a higher chance of getting cleaner air because the filtration capacity has been proven by international health regulations.
Intricate Air Filter Design
The design of the pleated HEPA air filters is such that it catches a range of particle sizes. Even if some of these particles are smaller than the air filter’s holes, the tangle of fibres in the mesh makes it impossible for the particles to pass through because the pathway is too narrow with the constant motion of the fibres.
What Is the Difference Between an Air Cleaner and an Air Purifier?
Though the answer is too obvious and both offer the same function, it is not the way you think. Air cleaners mainly work to ‘clean’ the air, filter it or collect particles like pet dander, dust or pollen. On the other hand, air purifiers ‘sanitise’ the air.
There is a great difference between clean and sanitised. You can say you’re clean because there is no presence of dirt, but it doesn’t mean you’re free of germs.
Air purifiers work with HEPA filters that trap or neutralise pathogens (bacteria and virus), pollutants, allergens (pollen, pet dander, carpet dust), mould spores and other toxic air (smoke). This makes HEPA air purifiers the gold standard among air purifiers.
What Are the Different Hepa Filter Types?
Do you know that HEPA filters have their own competitors in terms of their capacity to trap particles?
There are a variety of filters that can be used to reduce the amount of dust in your home. Some, like true HEPA (which meets government standards) are certified, efficient models.
Here are some of the HEPA filter classification:
• True HEPA
The air filter labelled as ‘true HEPA’ should conform to the standards for high-efficiency particulate arrestation (or ‘HEPA’) filters. The most efficient particle filter will remove up to 99.97% of all particles that are 0.3 microns.
• Absolute HEPA
It means the same thing as true HEPA air purifier, but with a higher filtration power (up to 99% and at >0.3 microns).
• HEPASilent
HEPASilent is a special kind of filter that captures fine particles by electrostatic attraction. This means you can use it to clean up dust, dirt and other impurities from your air.
• Permanent HEPA
The difference between a permanent and temporary filter is that the former can be washed rather than replaced, which means they last much longer. However, it’s important to note you should only use hot water when cleaning your HEPA filters because boiling may damage them over time.
• HEPA-Like
The performance of this particular type isn’t always up to par with the actual standard.
• HEPA-Type
The HEPA-type doesn’t mean anything by itself. They don’t all follow any set standard and can be confusing for consumers who want clarity on what they’re purchasing, HEPA filter wise.
RENSAIR: The World’s Best Air Purifier
If your search limits to a HEPA air purifier, it should be none other than RENSAIR. RENSAIR is a HEPA air purifier that can kill trapped pathogens in its filter. It works much better with its UVC lamp design that pairs with the filter material in eliminating harmful airborne particles.
