What are air purifiers?

Thus, they can offer a wide range of benefits for people with allergies or breathing-related conditions such as asthma.

Why should you buy a good air purifier?

  • Maintenance: Even the best air purifiers require frequent maintenance, mostly in the shape of filter replacements. Take into account how often you plan on using it, as the more you use it the more maintenance will be needed. Further, some air purifiers may have filters that have to be cleaned as well, while other have filters that need to be replaced.
  • Features: A good air conditioner doesn’t need to come with a host of additional features, although they can be certainly useful for many people. For example, you may want an air purifier with a timer or one that gives an indicates when the filter needs replaced.
What is the best kind of air purifier in the UK?

There are various types of air purifiers to buy, with the main difference relating to technology and filters utilized. Also, you will find air purifiers that range in size and shape, so there are many options to choose from when looking for the best air purifiers:

  • HEPA Air Purifiers: High-Efficiency Particulate Arresting (HEPA) filters are used in this type of purifier, which is considered the most efficient on the market. They cleanse up to 99% of air pollutants by capturing it in a fine mesh.
  • Carbon Filter Air Purifiers: These types of filters are often combined alongside HEPA filters due to their high absorption rate. This is achieved through the porous carbon material used in the filter, making this a great air purifier for tackling smoke, odors, and chemicals. However, this type of filter is less useful for people suffering from allergies, although it is usually combined with other an HEPA filter to address this issue.
  • UV Air Purifiers: By using UV rays this type of purifier is great for the removing of germs, bacteria, and other microorganisms. As it is less efficient at removing other particles from the air, it tends to be combined with other filters for maximum efficiency.
