I have narrowed it down to a couple of elements so you know what questions to ask yourself and what to look for:
- Asthma / Hayfever sufferer?
- Have pets & dander control
- Your Room Size
- To Ionize or Not to Ionize
- Type/Size of Filter
There are Three Main Types Of Air Purifier to choose from:
Ionizer air purifiers are generally inexpensive, but also the least effective air purifiers because they simply make the particles fall to the surface in the room. So your air will feel fresher, but the impurities/allergens are still in the room and open to inhalation. Nowadays an Ionizer is generally only found as an added extra on a Hepa Air Purifier. In general an Ioniser on its own is not the most effective way of cleaning a room, but an Ioniser as part of a Hepa Air Purifier is a good idea and a much more common sight nowadays. However, not suitable for use with birds so if you purchase a purifier with an ionizer make sure you are able to switch it off.
HEPA Air Purifiers ( High Efficiency Particulate Air Filter )
Hepa Filter air purifiers offer hugely better air cleaning efficiency than Ionizers. The contaminated room air is sucked into the machine and through the HEPA filter by a fan. The filter collects over 99% of the contaminants ( allergens,pet dander,dust mites, etc) and the cleaned air is then pushed back out to recirculate around the room. The upside of a good hepa air purifier is it's ability to filter out huge amounts of airborne contaminants for a relatively low cost. One downside however is the noise factor, a cheaply made Hepa machine can sound up to 10 times louder than an equivalent well made one. The more well known Hepa Filter brands like Bionaire for example tend to be quieter than the mass produced lesser known ones. The Blueair range of Hepa Air Purifiers are simply the most powerful, quiet and energy efficient units you can buy with awards galore from all over the world. With any Hepa based machine, you will need to replace the filters regularly to keep the air cleaning efficiency at it's highest level. So always check the replacement filter costs before buying. Many Hepa Air Purifiers now come with an Ionizer built in to offer the best of both worlds in terms of freshening the air and actually trapping the particles ( as opposed to simply depositing them on the nearest surface). You can also purchase a "Permanent" or "Lifetime" filter so you do not have to replace the filter every 6 months or so and indicates when it needs a clean with water and/or hoover).
Air Sterilizers (air sterilisers)
Air Sterilizers like the Airfree models are generally considered to be the Rolls Royce of air purification. These units clean the air to the highest possible degree and even destroy virus and bacteria. They are also completely silent in operation and have no filters to replace. The downside of an Air Steriliser is usually the initial cost being a little higher than other types, however the cleaner air and cost savings in not having to replace filters is definitely a huge benefit. Choose an air steriliser if you are concentrating your efforts on one specific room and want the cleanest air possible.
Just a bit of further info:
Pet Dander ( and especially Bird Dander ) can be a real nuisance. The trouble with bird dander in particular is that it is a very large particle and therefore clogs up the hepa filter in most machines very quickly. Replacement Hepa filters can be fairly expensive and for that reason, when dealing with pet dander it is wise to opt for an air purifier with a 'Lifetime Hepa'. Lifetime Hepa filters are unique in that they can be gently hoovered out and used again and again saving you a fortune in replacement costs over the years.
This information has been sourced from Breathing Space which I have found to be the most informative for choosing a air purifier.
I hope this helps fellow budgie enthusiasts who are looking to purchase a purifier.
