Allergies (allergic rhinitis, bronchitis, eczema, conjuctivitis) usually have one common trigger which is the contact of the person with the allergens (dust mite excrements, pollen, mildew).

Who (what) is to blame?

Sure, the general pollution of the environment is the first and major reason (allergies are considered the civilization deseases and the pollution comes hand in hand with the civilization development) but we can also blame our life-style.

Nowadys, people spend 80% and more of their time inside (their flat, office, restaurant, tube). For our body the (in terms of allergies) most dangerous are the smallest particles (viruses, scigarettes smoke, mite droppings) which circulate in the air and are inhaled (and in such closed spaces like flat/office/tube you exhale them and other people inhale them and vice versa). And also the average temperature in our buildings increased over the last 30 years by 4-5 Celsius degrees offering great living conditions for mites or bacteria.

Wet or dry vacuum cleaning?

In the 1990s, the wet vacuum cleaner producers came with the idea to win the battle with the dry vacuum cleaner producers persuading people that the dry vacuums are unable to catch as much microscopic particles causing allergies as the wet vac cleaners. It seemed logical for people. The wet vacuum cleaner sucks in the dust and the water catches and separates it. But the experimets have shown that the „truth is out there" and what works for larger particles doesn´t work for the smallest ones. Simply, the allergens were circulating in the air in the same amounts no matter if it was before or after the wet vacuuming.

So tell me - wet or dry?!

I - really - am not depreciating the abilities of the wet vacuum cleaner, I only state that water filter is not sufficient if it is the only filter your vacuum cleaner has. If you have a wet vacuum with the additional filters like HEPA, they probably do a great job and you do not have to change them for anything else.

I am allergic, so what vacuum cleaner should I buy?

In my opinion, the one that has Gore-Tex or multi-layer HEPA filter - no matter if dry or wet. They both (Gore-Tex and multiple HEPAs) are able to catch 99,99% of the loose dust particles and allergens.

To keep your flat clean it is necessary to vaccum it 3-4 times weekly (or 30-40 times if you have small children, let´s say 2-5 years old - I am joking, of course), not only the carpets and floors but also the beds, linen and furniture. It is also recommended to get rid of heavy, old curtains, drapery as well as grand-ma´s teddy bears or other plush toys. The buildings should not be over-heated and over-humidified

Standard flat inner temperature should not exceed 21 Celsius degrees during the days and 19 Celsiuses is enough for nights.

The average humidity should not exceed 50% and it is recommended to ventilate the room at least 2 times daily, in the morning and in the evening (take another sweater or glass of whisky - or both - and open all windows fully for at least 15 minutes).

If you have an allergic person in your household you should seriously consider the chance of buying an air purifier (not the humidifier, it only humidifies the air without cleaning it). With their performance and low noisiness they are much more effective than the wet vacuum cleaners.
