Air cleanser buying guide – must haves

HEPA Home Air Cleaners

  • Certain things are thought ‘must haves’ for a good air purifier. A very good air cleaner has, as an example, the relevant filters to get rid of or significantly lessen the types of pollution in your home you are focused on. The air cleanser will even should be able to complete a proper quantity of air changes inside the room you’re planning to utilize it in. Unfortunately, a massive greater part of air cleaner manufacturers are wilfully misleading in regards to the performance of these electronic home air cleaners. Things such as for instance filtration efficiency, quantity of air flow, noise level and what kinds of pollution the air cleaner can cope with are often obfuscated by many people manufacturers – either as they do not know much about air purification or because they do not want you to know the reality concerning the performance of these product. What filtration efficiency, airflow and sound pressure you might need, or suits you, hinges on your specific concern. We shall discuss each performance indicator in the section below in detail.

Air cleanser buying guide – nice to possess

Some top features of an air purifier are not absolutely necessary, but can be considered ‘nice to haves’. A filter life indicator is, as an example, a tremendously useful feature to own. The filter life indicator will notify you once the filters should be changed. Replacing the filters at the required time will make sure the air cleanser is performing as it should and protects the fan from being damaged.


  • Unfortunately, there’s no decent air purifier that is small adequate to fit in the palm of your hand and can 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 the size of a toaster to help you to do a suitable load of laundry. Similarly, you ought not expect an air purifier the dimensions of a toaster to help you to maneuver enough air to be able to properly purify an averaged size room. Casters can help allow it to be significantly simpler to move your air purifier around the house, particularly if you have got a unit that may handle considerable amounts of air. Handles are also useful, since it allows you to easily lift the machine from a single room to some other.

Handy Remote Control

  • Enables you to easily control and change the settings associated with the air purifier from a cushty distance, increasing accessibility.

Filter Availability

  • Unfortunately, we see it all the time that perhaps the big companies with household names make air purifiers without providing a guarantee for just how long you will be able to get replacement filters. Once the unit just isn’t selling well any longer, or they feel it’s time to “upgrade” it and change its looks and features, the model together with creation of the replacement filters for it are discontinued.

Timer Settings

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

Multiple Fan Speeds

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

Air purifier buying guide – maybe


  • Ionic home air cleaners are marketed as being quiet and efficient; however, they also tend to release ozone into any room, not making them ideal for everyone.

Ozone Generators

  • Be wary of home air cleaners which can be straight up ozone generators. These units produce huge amounts of ozone by design and form a serious threat to your health.


  • Some electronic home air cleaners use a filter density known as Ultra-Low Particulate Air (ULPA), claiming that is 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 type of filter technology does not take pollution from the air, but merely burns it. Burning dust as well as other pollution floating around does not directly result in cleaner air… also, whilst incineration will not allow you to move very much air quickly – a vital requirement for any decent air cleanser.

Air purifier buying guide – other things to consider


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

Filtration Efficiency

  • As you can see from the table below, different concerns require different filtration efficiencies. The greater filtration efficiencies are accomplished by HEPA or HyperHEPA filtration (provided that it pertains to your whole system filtration efficiency and not just a ‘theoretical’ filter efficiency) whilst lower filtration efficiencies are achieved from using filters with a lowered filtration efficiency such as for instance ‘HEPA-like’ or ‘HEPASilent’ filters. It’s very common that manufacturers usually do not display the particular filtration efficiency regarding the air cleaner in general, but only provide customers with a misleading theoretical filtration efficiency. If ionisation is employed it is worthwhile to know that the filtration efficiency will reduce steadily the more polluted the collection surface/filter gets. The performance for the unit can drastically decrease because of this. Furthermore, if the unit is certainly not leakage free, the amount of leakage will increase since the filters become more loaded too, further decreasing efficiency. Thus, some ionisers may have a higher filtration efficiency to start with but over time the filtration efficiency will gradually decrease.


  • The noise level will be different with respect to the speed setting the machine has been used on. You will need to think about your noise tolerance, and take into account where in actuality the air cleanser should be used. All proper air purifiers will produce some level of noise; depending on the speed setting the machine will be used on. However, you ought not 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 may not be pushing enough air to properly filter the air within the room it is being used in. One thing to be wary of is if manufacturers are not specifying the noise level on different speed settings of the air cleanser. It really is unfortunately quite common for some manufactures to promote their air cleanser only from the noise standard 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 once the unit is working arduaously harder, attempting to pull air through the filters.

  • Online investigation is a good idea; however, it is difficult to say how liable a source happens to be. Some sites are not particularly knowledgeable about air purification.

  • Regularly maintaining an air cleaner is essential so that the unit is working effectively. To experience maximum performance through the air cleanser you will need to replace the filters regularly. You should find out the cost and average life span of each filter before purchase. However, take into account that actual filter life will greatly depend on usage and contamination levels. Keep clear of electronic home air cleaners which require very frequent filter replacements. Also look out for 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, once the connection with past customers deserves some consideration. Some manufacturers and products are highly respected floating around purifier industry for a reason, building their portfolio through the years through products that work and providing great customer care. You will definitely always find manufacturers who make various claims about their products but have quite little to aid these claims.
