Air cleanser buying guide – must haves

HEPA Home Air Cleaners

  • Certain things are thought ‘must haves’ for a good air cleanser. An effective air purifier has, for example, the relevant filters to eliminate or significantly lower the kinds of pollution at home that you are concerned with. The air cleaner will also should be in a position to complete a suitable amount of air changes in the room you’re planning to make use of it in. Unfortunately, a huge almost all air cleaner manufacturers are wilfully misleading in regard to the performance of their air purifiers. Things such as filtration efficiency, number of air flow, noise level and what kinds of pollution the air cleanser can cope with in many cases are obfuscated by many manufacturers – either as they do not know much about air purification or as they do not want you to understand the facts in regards to the performance of their product. What filtration efficiency, airflow and sound pressure you require, or is right for you, depends upon your unique concern. We’re going to discuss each performance indicator when you look at the section below in detail.

Air cleanser buying guide – nice to have

Some options that come with an air purifier are not absolutely necessary, but can be considered ‘nice to haves’. A filter life indicator is, for example, a tremendously useful feature to have. The filter life indicator will notify you as soon as the filters need to be changed. Replacing the filters in the required time will make sure the air purifier is performing since it should and protects the fan from being damaged.


  • Unfortunately, there’s absolutely no decent air cleaner this is certainly small adequate to easily fit in the palm of the hand and may be carried around easily. Why don’t you? Well, there are limits to your physics of what is possible. You will not expect a washing machine how big a toaster in order to accomplish a proper load of laundry. Similarly, you should not expect an air purifier how big a toaster in order to go enough air to be able to properly purify an averaged size room. Casters can help make it significantly simpler to move your air cleaner throughout the house, particularly if you have got a unit that will handle large amounts of air. Handles are also useful, since it lets you easily lift the machine from one room to another.

Radio Control

  • Enables you to easily control and alter the settings of this air cleanser from a cushty distance, increasing accessibility.

Filter Availability

  • Unfortunately, we see all of it the time that even the big companies with household names make electronic home air cleaners without providing a warranty for just how long you are able to acquire replacement filters. When the unit just isn’t selling well any more, or they feel it is the right time to “upgrade” it and change its looks and features, the model therefore the production of the replacement filters because of it are discontinued.

Timer Settings

  • Turning the unit on / off during times during the the day/week, allows you to save energy and prolong the filter life.

Multiple Fan Speeds

  • Affect the speed setting to your preference, to suit your indoor pollution level or sound preference.

  • Ionic air purifiers are marketed to be quiet and efficient; however, they also have a tendency to release ozone into any room, not making them ideal for everyone.

Ozone Generators

  • Keep clear of electronic home air cleaners which are straight up ozone generators. These units produce large amounts of ozone by design and form a significant threat to your health.


  • Some air purifiers use a filter density referred to as Ultra-Low Particulate Air (ULPA), claiming this is certainly better than HEPA (High Efficiency Particulate Air). These filters drastically reduce airflow and also as such limit the performance regarding the air cleaner.

Incineration and Combustion

  • This kind of filter technology does not take pollution out from the air, but quite simply burns it. Burning dust as well as other pollution floating around will not directly lead to cleaner air… also, whilst incineration does not allow you to move quite definitely air quickly – an integral requirement of any decent air cleaner.

Air purifier buying guide – other factors to consider


  • Any air cleaner you buy in the united kingdom should come with a 2 year warranty; some air cleanser manufacturers attempt to sell you additional extended warranty or make an effort to get the contact details in return for additional warranty. Be sure to check what the warranty covers, such as motor/ fan, display, other electrical components and labour. Consumables, such as for instance filters are normally not covered by an air purifier warranty. Also, make sure to verify that customer action will void the warranty. Most warranties will as an example only apply to the first purchaser regarding the unit and won’t transfer to subsequent owners.

Filtration Efficiency

  • As you care able to see through the table below, different concerns require different filtration efficiencies. The bigger filtration efficiencies are accomplished by HEPA or HyperHEPA filtration (so long as it pertains to your whole system filtration efficiency and not only a ‘theoretical’ filter efficiency) whilst lower filtration efficiencies are achieved from using filters with a lesser filtration efficiency such as for example ‘HEPA-like’ or ‘HEPASilent’ filters. It is extremely common that manufacturers usually do not display the specific filtration efficiency regarding the air cleaner in general, but only provide customers with a misleading theoretical filtration efficiency. If ionisation is employed then it is worthwhile to learn that the filtration efficiency will decrease the more polluted the collection surface/filter gets. The performance of this unit can drastically decrease this is why. Furthermore, in the event that unit just isn’t leakage free, the degree of leakage will increase because the filters become more loaded too, further decreasing efficiency. Thus, some ionisers could have a high filtration efficiency to start with but as time passes the filtration efficiency will gradually decrease.


  • The noise level will be different with regards to the speed setting the system will be utilized on. It is essential to think about your noise tolerance, and take into account where in fact the air cleanser is likely to be used. All proper home air cleaners will produce some standard of noise; with respect to the speed setting the machine will be applied to. However, you shouldn’t compromise the cleaning performance associated with the unit for the comfort of reduced noise levels. An admirer that is too small or this is certainly moving too slowly might not be pushing enough air to properly filter the air inside the room it is being used in. One thing to keep clear of is when manufacturers are not specifying the noise level on different speed settings regarding the air cleanser. It is unfortunately quite common for some manufactures to market their air cleaner only regarding the noise level of the quietest settings. Depending on the technology used, some electronic home air cleaners are quiet at first but become noisier the more used the filters are. If the filters are loaded, then your unit will emit more noise whilst the unit is working arduaously harder, attempting to pull air through the filters.

  • Investigating online is a good idea; however, it is often hard to say how liable a source really is. Some sites are not particularly proficient in air purification. Some formerly independent review sites have already been bought by air cleanser manufacturers, and from now on wanting to promote their own products as the best. Here is a listing of sites which do independent air purifier testing:
  1. Consumer Search
  2. Consumer Reports
  3. Best Buy

  • Regularly maintaining an air cleanser is important so that the unit is working effectively. In order to achieve maximum performance through the air cleanser it is important to replace the filters regularly. You should find out of the cost and average life span of every filter before purchase. However, take into account that actual filter life will greatly rely on usage and contamination levels. Be wary of home air cleaners which require very frequent filter replacements. Also be aware of electronic home air cleaners which require you to clean/or wash the filters.

Manufacturer’s Reputation

  • The manufacturer’s reputation is an important deciding factor, as the connection with past customers deserves some consideration. Some manufacturers and items are highly respected in the air purifier industry for a reason, building their portfolio through the years through products which work and providing great customer service. You will definitely always find manufacturers who make various claims about their products but have very little to aid these claims.
