Air-purifying Solutions: A Lowdown

Thinking about getting an air purifier? There’s lots of air purifying solutions available now, especially with air purifying paint added to the mix. Let’s compare and see why air purifying paint is a great complement, even as it works well on its own!


Maybe it’s not as fierce as US partisan politics, or whether that dress was black/blue or white/gold. But the debate between air purifiers and air-purifying solutions is worth exploring.


Like every product and service in the business world, all air purifiers have to show off their best sides. (In our case, we do it with paint!) But the central concern for you, dear reader, doesn’t change. “I don’t want air pollution to harm my living spaces and my loved ones.”


It’s good to know the whole picture when deciding which solution works best for you. With so many different purifiers available, we’ve laid out the pros and cons of different air purifying technologies. Hopefully, we’ll help you decide: what’s the air-purifying solution for me?


High-Efficiency Particulate Air technology has been around since WW2. It was used in masks to protect wearers from chemical contaminants. Only in the 60s did it begin to have more uses in a household. HEPA purifiers use filters that trap fine airborne particles (down to 0.3 microns), removing them from the air. If you’re getting a HEPA purifier, you’ll want to take note of the Minimum Efficiency Reporting Value (MERV). The higher it is, the more particles it’s able to trap. 


The strength of HEPA is in its ability to trap particulate matter effectively. However, it doesn’t work so well for smaller pollutants, including VOCs, bacteria, viruses and mold spores. These are too small for the HEPA filters to trap. The filters are also fragile, and you’ll need to replace them if damaged or used too long.

Some HEPA purifiers are paired with Ozone-Generating technology. It’s an effective way to remove odours and break down pollutants. It’s similar to how the sun makes your clothes smell better. But as ozone particles are extremely reactive, they are not good for your health. As such, ozone purification is used mainly in commercial settings with minimal human presence.

Ultraviolet light has disinfecting qualities which have been used in germicidal, healthcare and water treatment processes. Essentially, it alters the DNA of microorganisms, rendering them harmless. However, the main concern around UV purifying technology is the formation of ozone in the process. As we mentioned, this isn’t good for our health and environment. Microorganisms like mold spores have also been shown to aggravate asthma and allergies even after being deactivated by UV.

Carbon Filters 

A conventional technology incorporated into many air purifiers. Carbon filters use activated carbon that absorbs VOCs and airborne pollutants effectively. It also doesn’t release harmful byproducts in the process. However, carbon doesn’t break down the pollutants it absorbs. Once the filter is saturated, the pollutants can escape and enter the air again. Regular replacement of the filters is required to ensure the effectiveness of this technology. Also, not being effective in trapping particulate matter, it is usually paired with a HEPA filter.

Negative Ions 

This technology is usually found in electrostatic precipitators and air ionizers. Their main draw is that they’re filter-less. Instead, they use charged plates that cause ions to attach to particles as they pass through. This causes the particles to become heavy and sink to the ground.


However, the effectiveness of negative ions is limited. And, if compensated by releasing more ions, the chance of ozone being created increases. There is also a need to clear the loaded particles before they are stirred up into the air again. 


Here’s a video for all the visual learners that tries to simplify the differences between an ionizer and an air purifier!

The air ionizer creates a charge around the air particles floating in the room. Once charged, these particles become heavy and stick to the ground or on other surfaces.

Water-Based Purifiers 

Usually cheaper than other air purifying technologies, these are easy to maintain. Simply replace the water regularly. By filtering the air through water, pollutants are removed while also giving your space fresh air. You get an environment similar to the clean feeling after rain. However, they are limited in their effectiveness at removing all pollutants and odours. Also, because moisture is involved, this could feed microbial growth if left unchecked. 

The distinctive feature of a water-based purifier is its inlet vent that allows purified air to be passed to be released into the environment.

What about air purifying paint?

A great question, and one that actually sparked our innovation of air purifying paint!


With so many air-purifying technologies today, picking the one for you depends on key factors. Decide your budget, your expectations of maintenance and the primary pollutants you wish to remove. gush air-purifying paint provides an all-round solution that works 24/7 without electricity. It even goes a step further, by breaking down pollutants rather than merely trapping them. Also, you’ll get to pick from a wide array of colours!


You can complement your air purifier of choice with a space painted with cair or cair fresh. The key is to combine good air flow with the large surface area covered by paint. This ensures any pollutants finding their way into your spaces will contact the walls and get broken down quickly. Now you’re breathing easy, in a safer, healthier and cleaner space!
