Brief conclusions of the comparison vacuum cleaners

Both Bosch Cleann n vacuum cleaners BGS 05A225 and BGS 05A221 have similar features: 700 W power, a cyclone dust collector system with a capacity of 1.5 L, and a HEPA filter. Both devices are designed for dry cleaning and equipped with a telescopic tube, with a noise level of 78 dB. However, according to user reviews, the BGS 05A225 model is more accessible in the market, while the BGS 05A221 is currently unavailable for sale. Additionally, the BGS 05A221 is presented in turquoise, whereas the BGS 05A225 is in white. Both vacuum cleaners come with a combination, crevice, and dust nozzle set, making them versatile for different types of cleaning.

Fine filter

The presence of a HEPA fine filter in the vacuum cleaner; also in this paragraph, the specific class of this filter is often specified.

HEPA (High Efficiency Particulate Absorbing) filters are designed to purify the air from the smallest mechanical contaminants — up to tenths of a micron in size. It allows you to trap not only fine dust but even bacteria. For comparison: the size of most bacteria starts at 0.5 microns, and the effectiveness of HEPA filters is evaluated by the ability to retain particles with a size of 0.1 – 0.3 microns. The most advanced such filters ( class 13 and above) are able to remove more than 99.9% of these particles from the air. Here is a more detailed description of the different classes:

— HEPA 10 – traps at least 85% of particles with a size of 0.1 – 0.3 microns;
— HEPA 11 – at least 95% of such particles;
— HEPA 12 – not less than 99.5%;
— HEPA 13 – not less than 99.95%;
— HEPA 14 – not less than 99.995%;

Note that pollution with a size of 0.1 – 0.3 microns is the worst-kept by HEPA filters, so with particles of other sizes (both larger and smaller), the efficiency of such elements will be even higher.

Regarding the choice for this parameter, it is worth noting that, in fact, it does not always make sense to pursue a high filtration class. For example, during wet cleaning with a washing vacuum cleaner (se...e above), the HEPA filter, in fact, is not needed at all (in many models, it is recommended to remove it altogether for such cases). So if you plan to use such a vacuum cleaner mainly for washing, you can ignore this parameter. Another specific case is industrial units (see "Type"): they are often used for rough cleaning of large debris, where thorough air filtration is not required.
