Key things to look out for in an Air Purifier

One of the key points to consider in the operation of an Air Purifier is the CADR rate. CADR is an acronym for Clean Air Delivery Rate. In general, this numerical value will indicate the quantity of particles to be removed from the air. Basically, a CADR rating indicates how fast the air purifier can clean the air within a particular size room by cubic metre per hour (cm/h). For example, an air purifier with CADR rating of 300 cm/h will clean a room of 300 square metres much faster than an air purifier with CADR rating of only 200 cm/h.

A CADR measurement is usually evaluated for pollen, smoke, and dust. These three pollutants are not only small in size but also the most unwanted particles in the air. Smoke particles are ultra-fine particles, with the defined particle size ranges from 0.1 to 0.3 microns. Dust particles are common particles with size from 0.5 to 3 microns. Pollen particles are the large particles which can usually be seen with the naked eye, with size from 5 to 11 microns.

Air filtration (filters) are also a critical element of air purifiers. Importantly, Welcare PureAir air purifiers use HEPA13 filters.

The HEPA13 filter is a medical-grade air filter which can remove all particles of 0.21 microns and larger with 99.95% efficiency. Common consumer air purifiers use H11 and H12 standard HEPA filters, which can trap 0.3-micron particles at 85% to 95% efficiency. Medical-grade filters, including HEPA 13 filters, are commonly used in airplane cabins, semiconductor fabrication plants, pharmaceutical plants, and hospitals. The reason why they are used in these environments is because they have a higher particulate capture rate.

Importantly, not all HEPA filters are the same. There are many types of air filters which are claimed to be of high-grade filtration – ‘True HEPA’, ‘HEPA-like’, ‘H13 HEPA’, and ‘Medical-Grade HEPA’. The question is – are all these the same kind of filter, or are there differences between them?

“(HEPA filters) remove at least 99.97% of airborne particles 0.3 microns (μm) in diameter. The filter’s minimal resistance to airflow, or pressure drop, is usually specified around 300 pascals (0.044 psi) at its nominal volumetric flow rate.” (DOE)

In short, HEPA filters capture small particles like dust, pollen, mold, smoke & pet dander (pet hair)

‘True HEPA’ is simply a marketing term which companies producing HEPA filters have developed over the last decade. There is no difference between an air purifier with True HEPA vs HEPA filters; it’s just that True HEPA was tested to sound better in consumers’ ears.

There are different classes of HEPA filters, according to the EN 779 normalisation standard. Classic HEPA filters are usually H10, H11, or H12 class. The best HEPA air purifiers will use H12 or higher rated HEPA filters.

Importantly, HEPA 13 (or H13) are even better than normal HEPA filters. Specifically, the H13 filter captures particles that are more than 3x smaller than classic HEPA filters.

HEPA 13 filters remove at least 99.9% of airborne particles 0.1 microns (μm) in diameter.

Accordingly, when compared to HEPA or True HEPA, HEPA13 filters remove even the smallest particles which True HEPA filters are unable to capture. This includes asbestos particles, paint pigments, insecticides, and so on.

HEPA 13 filters are so thorough they are used in clinics, hospitals, and dental offices.

What’s the difference between the H13 HEPA filters and Medical-Grade HEPA filters?

There is none. The bottom line is H13 HEPA filters are simply so thorough they are used in medical settings; hence the name ‘Medical-Grade’.
