The exposure to dust and fine dust is increasing
Normally, regular ventilation is the best way to keep your home away from too much dust. Unfortunately, the outside air is no longer really clean in many areas. The high levels of particulate matter in our cities is not only present in the news, we can literally smell it too. The health damage to the heart and lungs, for example, caused by fine dust is well known.
If you live on a busy street, ventilation does not improve the air in your room; you only get more dust into your apartment. In winter we rarely ventilate, sometimes we spend the whole day in closed rooms without a breath of fresh air.
The dangerous thing about fine dust is that it settles in the lungs and can no longer be breathed out so easily. If you constantly inhale fine dust, the lungs are "dusted" layer by layer. The lungs can only regenerate and break down the accumulated dust if they repeatedly get a “breathing space”. An air purifier against dust is definitely one for each of us sensible investmentto improve the air in his home or office and protect his health.
What is dust anyway and how is it created?
Although dust usually looks the same to the naked eye, dust consists of many different particles. It is not possible to make a precise distinction between house or coarse dust and fine dust. The transitions are fluid, there are dust particles of every size.
- Natural dust particles are created by the erosion from rock, sand, other minerals (for example from mountains or deserts) or through volcanic ash.
- Dust can too of vegetable, animal and human origin and consist of plant pollen, fungal spores, microorganisms, hairs and flakes of skin.
- Dust is created in the combustion All kinds of substances, forest fires, but also fires in open chimneys and wood heaters (and candles!) cause large amounts of fine dust. In the same way, cigarette smoke is a bad producer of fine dust.
- A significant proportion of the fine dust pollution is exhaust gases from the Car, air and ship traffic attributable to. In addition to the exhaust gases, a lot of dust is also created by the abrasion of tires and brake pads on the road. It is no coincidence that cities with lots of traffic jams and stop-and-go traffic (such as Stuttgart) have the highest levels of particulate matter.
- Industrial companies and power plants blow masses of dust into the air we breathe through their chimneys.
- Building materials, paints and chemical substances on and in buildings decompose to dust, some of which is highly polluted.
- We also produce dust in our own apartments, for example when cooking and roasting. Lately it has been known that specifically Laser printer can cause extremely high levels of particulate matter in the room air.

Filtering out dust with the air purifier - which models are best?
Almost all air purifiers work in a similar way to a vacuum cleaner: They draw air into the device electrically via a fan, so that dust and other particles get caught in the air purifier. They can basically be divided into three types: Air purifier with filter system, air washer and ionizers. Some models combine these technologies. Which device you choose depends on your goal, how complex the operation of the devices can be and how much money you want to spend.
Air purifier with filter systems
The filter systems of air purifiers are very diverse. Most devices use a combination of different types of filters: For example, coarse pre-filters, activated carbon filters and HEPA filters. Special HEPA filter are highly effective filters that prevent even the smallest particles from passing through. When the air purifier filters dust from the air, it simultaneously frees the room air from many pollutants, mold spores, odors and even bacteria and viruses.
From cheap to extremely expensive, the available range offers something for everyone. The big, unfortunately unavoidable disadvantage of such air purifiers is the high running costs for the replacement filter. Depending on the model and intensity of use, you will have to replace individual filters or the entire filter system after a few months. Some of the filters cost more than 50 euros.
In terms of filter performance, such air purifiers are the ultimate. If you not only want to keep your apartment dust-free, but also all around germ-free and pollutant-free air Value should you choose a filter-based air purifier model.

Air washers are also suitable as air cleaners against dust. They act like a permanent downpour that washes the dust out of the air. Inside there is a roller that is permanently moistened with water. The room air is directed past the roller. Coarse dust particles - also animal hair or pollen - stick to the roller and are washed off in a water basin. The passing air becomes additional moisturizes.
Fine dust or pollutants, however, are not bound well in the water and go back into the air. The water in air washers must be changed every one to two weeks to prevent germs from developing. You don't have to change or buy filters for this. Some air washers also have a pre-filter in which coarse dust particles or hair get caught. This way the water stays clean a little longer. Air washers are therefore recommended if you only want to roughly filter your room air and humidify your room air and you do not mind regular cleaning.
Air washers are not recommended, especially for those with house dust mite allergies, because too high humidity (> 50%) promotes the reproduction of mites.
A popular model is the LW 220 air washer from Beurer, which is suitable for rooms up to 40 square meters.
Ionizers (sometimes called ionizers) are one relatively cheap solution to fight dust with an air purifier. They charge the room air and the dust particles and pollen it contains electrically. As a result of the charge, these particles combine to form “lumps” and, due to their higher weight, fall to the ground.
If you don't vacuum regularly or move around the room a lot, the dust is easily kicked up again. Some models therefore attract the charged dust particles via a metal plate and trap them in a container. Ionizers are very easy to maintain, you only have to empty the dust container every now and then.
Ionizers as air purifiers against dust are, however controversial. Ozone is created as a by-product of the electrical charge. In high concentrations it can irritate the respiratory tract or cause headache. It is therefore essential to find out more about how to use an ionizer against dust correctly.
The Tevigo air purifier / ionizer for rooms up to 45 square meters is currently one of the best sellers.
