Air purifier buying guide

Dandelion Blowing In WindSo you’re looking for an air purifier – you want cleaner and fresher indoor air, but you’re not sure what you need. We’re here to help! Let’s look at the most common types of air purifiers and hopefully you’ll find out which one is best for you.

Activated Carbon Air Purifier: activated carbon (sometimes referred to as activated charcoal) is so called because it has been treated to be more porous and have greater surface area. What this means for an air purifier is an absolutely excellent capacity to absorb pollutants. Carbon filtration is so effective it is widely used in medical and industrial applications, as well as water and air purification.

Activated carbon air purifiers are best suited for absorbing toxic gas or vapours like VOCs, cigarette smoke, dry cleaning chemicals, fuel vapours etc… A carbon air filter is sometimes called a Deodorisation filter since it leaves the air cleaner and smelling fresher!

We stock a few carbon air purifiers – the smallest and cheapest is the Ionmax Desktop – we’ve also got a Coway Nano-Silver carbon purifier, and the NanoBio range – the newest additions to our catalogue!

Filterless ionic air purifier: sometimes called negative ionizers, this type of air purifier is usually quieter than its counterparts and does not use a fan to run. Instead of filters, an ionic air purifier has collection blades (usually made of steel) and a built-in negative ion generator. The negative ions clump to airborne pollutants and change their electrical charge, causing them to stick to the collection blades or fall to the floor ready to be vacuumed.

An ionic air purifier requires no maintenance other than weekly or fortnightly wiping of the collection blades with a damp cloth. It is also economical in the long run since no filters ever need replacing. People often report feeling energised while having an ionic air purifier running, as an increase of negative ions in the air is revitalising (high negative ion density is found in unpolluted environments like forests).

We stock a variety of ionic air purifiers: from fridge or pantry sized to night light to Midi Tower, there’s bound to be one perfect for your needs! We even have an ionic car air purifier that plugs into the cigarette lighter (need we point out it is so much better for your health?!).

Hepa air purifier: probably the best allergy air purifier there is. A Hepa air purifier is perfect for asthma sufferers or those combatting hay fever symptoms throughout the year. Hepa stands for High-Efficiency Particulate Air and as the name suggests, Hepa filters are designed to trap microscopic airborne allergens and pollutants as small as 0.3 microns with fierce efficiency.

In fact, true Hepa filters capture 99.97% of particles 0.3 microns or larger that float through the air. The secret of a Hepa filter’s effectiveness lies in its composition: a Hepa filter is made of thin fibres in a random pattern – microscopic airborne pollutants passing through become trapped and lodge directly into its fibres.

Pet Brush With Pet HairOur Hepa air purifiers have been certified by Allergy UK (formerly the British Allergy Foundation), and are capable of cleaning the air of pet dander, fungi, moulds, and dust mite faeces to name a few – all typical allergy-triggering pollutants.

UV air purifier: UV air purification relies on germicidal uv light to irradiate and kill airborne pollutants. UV air purifiers can be filterless and target the collector blades in ionic air purifiers, or have their UV light positioned in between air filters to kill pollutants as they pass through.

UV light sterilises the air by effectively targeting the DNA of microscopic pollutants. A UV light air purifier can destroy fungi, moulds, viruses, and bacteria.

We stock both a filterless UV ionic air purifier and an activated carbon UV air purifier. UV air purification is economical: the average lifespan of a uv germicidal lamp is several thousand hours.

So hopefully if you need a little help from an air purifier to achieve cleaner air at home, now you know which one will work best. If not, get in touch and fire your questions away: we’re always happy to help!
