What is a Humidifier?

Humidifiers are the antithesis of dehumidifiers. As the names suggest humidifiers increase the amount of humidity in the air whilst dehumidifiers decrease the humidity levels.

what does humidifier do?

Humidifiers are typically used when the air gets too dry or stale and makes it difficult to breathe such as when the weather is really dry or in winter time when the radiators have been on for much too long.

Some people even use humidifiers too keep sickness and flu at bay however, be warned that extended use of a humidifier could make respiratory problems worse.

Symptoms of Dry Air

The ideal use for a humidifier is if the following symptoms are present:

  • dry skin
  • flaky skin
  • blood noses
  • dry throat
  • dry cough
  • sinus congestion
  • Nasal problems
  • cracked lips

You will note that all of these problems can be the result of dry air. As stated above a humidifier can increase the moisture levels which can alleviate the above symptoms.

Humidifier Know-How

It is important not to use a humidifier in a house which has had water damage as damp problems such as mould and fungi etc are likely to grow. If the property is rented make sure that you ask the landlord about the history of the property before using a humidifier.

Together with your humidifier you should also purchase a good hygrometer to keep an eye on humidity levels in your property. The typical relative humidity level of a home should be around 50-55%. If your humidity level is above this you run the risk of increased:

  • dust mites
  • mould
  • other fungi
  • harmful bacteria

 How Humidifiers Work

The best humidifiers work through a process of ionisation. The humidifier pulls in positive ions such as dust, dirt and pollens and charges these with negative ions which causes the enlarged ion to become too heavy to be airborne.

As you can imagine this process is of great benefit to those with allergies.

I personally think that, in the British Isles, a dehumidifier would be a better purchase than a humidifier especially if the dehumidifier features an anti-bacterial filter and ioniser.

Two such dehumidifiers with these features are the EcoAir DD122MK5 and the Meaco DD8L.
