What we consider when we recommend
Dust and dirt in the indoor environment contains a variety of particles that can impair our health. Airborne allergen such as pollen, mites particles and fur animal epithelium are the most common particles that can cause problems for people with allergies. It is therefore important that vacuum cleaners efficiently take up and separates even very small particles which otherwise risks irritating airways and mucous membranes.
Vacuum cleaners, equipped with filters, can clean the exhaust air so that it contains fewer particles than the ambient air. It is therefore important to have a good filter system in a dense vacuum cleaner so that dust does not leak when changing bags and filters. Once the dust is collected, it should not spread again, therefore, the vacuum cleaner should not swirl particles in the air during vacuuming. This also reduces the risk that the vacuum itself will affect the health of persons with sensitive airways, including asthmatics.
Dust collection and filtration together constitute the efficiency of the vacuum cleaner. Parameters that affect efficiency are as follows:
Density of the vacuum system
Replacement/cleaning of bags/filters
Filter efficiency/filtering efficiency
The fraction separation level of 0.3 - 0.5 μm should be ≥ 99.98% of the number of particles. Vacuum cleaner bags must be sealed. Cleanable filters are not accepted.
Noise level, sliding resistance, manageability and ergonomics are not the most important characteristics from an allergy perspective. But since users easily avoid vacuuming if it is inconvenient, noisy and difficult, these parameters can indirectly affect the buyer's choices and ways of using the vacuum cleaner positively. Contact surfaces on the vacuum cleaner that release nickel can also create problems for individuals with contact allergy. The nickel content shall be below the limit of current EU regulations
We therefore also consider the following parameters before a recommendation:
