Planning to buy an air purifier? 5 things to consider | Technology News – Knoow.in

With air quality now crossing dangerous levels in several parts of India, air purifiers have shifted from being a luxury to a necessity. They are particularly helpful if someone in your household has severe dust allergies or other respiratory conditions. Additionally, air purifiers are easy to maintain and use for extended periods of time due to their very simple construction.

Investing in a high-quality air purifier significantly enhances the health and comfort of living spaces, prompting consumers to carefully evaluate these features when making a purchase. In light of this, here are some characteristics to consider when purchasing an air purifier.

1. HEPA filter

Anyone who is allergic to dust or pollen must have a HEPA (High-Efficiency Particulate Air) filter. With an efficiency of 99.97%, HEPA filters are made to filter out particles as fine as 0.3 microns, such as dust and pollen-sized items, as well as bacteria and mould. The majority of air purifiers come with an air filter, but to make sure they are HEPA-certified.

2. Odour removal capabilities

The ability of some air purifiers to eliminate odours from the air is a characteristic that is often disregarded. Certain purifiers have carbon filters that capture and remove offensive smells. When searching especially for this feature, keep in mind that these filters are typically on the expensive side.

3. Air quality sensor

Another beneficial feature for air purifiers is the inclusion of an air quality monitor. Traditional air purifiers filter air continuously at a constant rate but lack the capability to detect sudden fluctuations in air quality, such as those caused by smoke or construction activities.

4. Fan noise levels

Choosing an appropriate air purifier is crucial for maintaining indoor air quality, as these devices function most effectively when operated continuously. It is advisable to select models that are both quiet and efficient, minimizing disturbances during sleep or daily activities. Although manufacturers typically provide noise level ratings online, experiencing the sound of various air purifiers in person at retail locations is beneficial.

5. Filter indicator

The filter life indicator is crucial for assessing the efficiency of an air filter in purifying air. It works by monitoring the air pressure at the filter as air passes through, tracking degradation over time to determine the filter’s level of clogging or damage. Given their delicate nature, these filters degrade over time, making timely replacements essential for ensuring that the air you breathe is adequately filtered. Failing to replace the filters can render the air purifier ineffective, making it similar to merely using a fan to circulate air.
