Air purifiers can positively affect your daily mood and freshen stale air, lowering the risk of health problems from indoor contaminants, which can cause respiratory infections, neurological disorders, or exacerbate asthmatic symptoms. Good air purifiers remove various indoor air contaminants, preserving our health.
It works by sucking in the air using an internal fan system, having that air pass through its filters and trapping pollutants like pollen, dust, and bacteria before dispersing the filtered air back into the room. This filtering procedure keeps the internal airflow healthy.
However, not all air purifiers are made equal. Here’s what to look out for when you’re purchasing an air purifier for home.
1. HEPA Filters
Avoid purifiers with “HEPA-like” or “HEPA type” filters and look for actual HEPA filters instead. Due to their ability to trap tiny germs, true HEPA filters are the most effective in cleaning the air. Try using air purifiers with HEPA and activated carbon filters if you also wish to prevent smells and gases.
At Wells, most of our air purifiers are fitted with an H14 Zero Clear HEPA filter which eliminates 99.997% of 0.3µm ultra-fine dust and nanoparticles in the air. With our Wells Tornado, you can even eliminate up to 99.999% of 0.01µm (ultra) fine dust. They also come with customised filters for various needs, such as the deodorisation filter for those concerned about foul odours and the pet filter for those with fur babies.
2. Noise Level
Choose air purifiers that can effectively clean your air at low noise levels to prevent sleep interruptions. Most air purifiers with HEPA filters emit 35 to 70dB of noise. Depending on your operational parameters, the noise level will vary.
Our Wells Interior is a custom-made air purifier for study rooms and bedrooms and optimised to be silent. It can keep its fan activated at 28dB, which is quieter than a library (Library Noise Standard: 40dB), creating a conducive environment for working or studying.
3. Size Compatibility
Different air purifiers are made to purify the air in various-sized rooms. When purchasing an air purifier, always check with your sales consultant about the size compatibility. An air purifier operates optimally when it is suitable for the size of your space. Invest in a model that is effective in a larger room so that even when you use a lower setting, the air purifier can still clean your air effectively. This will help you save on energy costs.
When purchasing an air purifier, you should also consider the maintenance cost. Depending on how frequently you need to replace your filter, maintenance expenses will change. Your HEPA filter usage should be taken into account when calculating energy costs. Washable filters are a feature of certain air purifiers, such as those with UV capabilities, but they require more power to operate, which will cause your utility bill to increase. Furthermore, many germs are UV-resistant, so UV light air purifiers might be less effective than air purifiers with HEPA filters.
Air purifiers with HEPA filters are energy-efficient, but for the best results, you should replace the filters every three months. You may have to spend more on filter replacement if you get an air purifier with many filters. For instance, replacing the HEPA and activated carbon filters in your air purifier every three to four months may wind up costing you more than $100 annually.
Getting an air purifier is your first step to living with cleaner and fresher air. However, with many different types of products and technologies in the market, it can be challenging to decide which one to go for.
At Wells, our air purifiers for dust in Singapore come with different functions and capabilities to accommodate your needs. With essential features such as built-in sensors that measure the air quality and a Smart Purification Mode that operates on its own based on the contamination check, clean air is a breeze.
Aside from air purifiers, Wells also specialises in water purifiers and water dispensers in Singapore that guarantee clean drinking water. Get in touch with us today to find out more!
