What Makes an Air Purifier Better than Others?


Take a deep breath, if you can. Most of us buy air purifiers to improve the overall air quality by removing most microscopic pollutants in the air inside our homes. But despite product claims, not all air purifiers can deliver the same results and levels of purification.

Each air purifier model has a definitive set of technical specifications and functionalities. Therefore, every model has its fair share of standouts and limitations. Here we discuss some of the features of top-notch air purifier designs that place them a cut above the rest so that you can select the best air purifier for your home. Take a look.

1. Multistage Filtration Process

Note that the air purifier must contain more than one filter to remove most types of particulates, gaseous pollutants and VOCs from the air inside your homes. While most air purifier models feature a twin-filter assembly to remove specific-sized particulates and compounds, there are designs such as HealthPro 250 from IQAir, which feature a three-stage filtration process.

These purifier designs typically include a pre-filter that removes coarse and fine particulate pollutants such as pollen, mould spores and pet dander. Further, these models feature an advanced gas and odour filter, made up of activated carbon and impregnated alumina to remove a wide variety of unpleasant odours and gaseous pollutants.

Most importantly, however, these designs comprise a HEPA filter that eliminates all types of ultra fine particles including PM2.5, PM10, bacteria and virus to make the air inside almost perfect for breathing.

2. HEPA Filtration Technology

HEPA (High-Efficiency Particulate Air) filtration is the benchmark for quantifying the effectiveness of an air purifier. Recognised by the United States Department of Energy (DOE) as the standard of air filtration, it requires purifiers to be able to remove at least 99.97% of the particles, more than or equal to 0.3 µm (micrometre) in size.

That said, there are designs such as IQAir’s HealthPro 250, which feature the Hyper HEPA technology to filter out ultrafine pollution particles, as small as 0.003 microns in size, and that too, with a guaranteed efficiency of over 99.5%.

Further, IQAir’s HyperHEPA filter is the first-ever residential air filter to be tested and certified with European Norm EN 1822, which is the most stringent test standard for air purifier filters in the world.

3. High Performance Noiseless Application

Along with the filters, the fan motor is another essential constituent that defines the efficiency of a top-rated air purifier. The fan is responsible for directing the impure air through the filters. Therefore, more powerful the fan motor more quickly is the purifier able to sanitise the air inside your home.

Top-ranking purifier models from reputable manufacturers such as IQAir feature high-performance fan motors that have a free-flow rate of 1200 m3/hour or more and are designed for non-stop usage.

Another standout feature about these designs that distinguished them from others is their smooth and quiet operation. Typically, premium-range air purifiers have a noise output of 50dB or less for extended usage.

Such low noise levels are possible because of the fan-incentre designs, which mean that the fan motor is placed between sound attenuating filters, which effectively reduces sound transmission. Also, these purifiers feature rubber suspension pads that systematically isolate the motor vibration from the casing of the purifier.

4. An Air Purifier Can Help Make A Difference

Each air purifier is different from its peers regarding design, modularity, functionality and efficacy. While some purifiers are efficient in purifying the air inside smaller homes, others are more suited for large halls, bedrooms and living room spaces.

Therefore, you need to look for certain design aspects and standout features of each air purifier model that fits your budget range and compare them with each other. The most important feature that can serve as a viable metric for differentiation is HEPA filtration. The better the purifier is in removing ultrafine particles such as PM2.5 and PM10, the more efficient it will be in improving the air quality inside the home.

Apart from this, there are other determinants such as portability, noiseless operability, aesthetic appeal and ease of use that help you determine which purifier design is a notch above the rest. Remember, you cannot put a price on your family’s health. Therefore, it is advisable to go for a premium-range air purifier instead of settling for any other design.

Purifier models such as those from IQAir are designed to deliver high-performance over prolonged usage while maintaining the appropriate standards of efficiency. To buy the best air purifier for your family, you can contact BreatheEasy – the official and exclusive partner for IQAir in India.
