Filters, seals and maintenance: the "secret" to maintaining suction.

Filters, seals and maintenance: the "secret" to maintaining suction.

Many mini vacuum cleaners “seem great” for the first week and then lose power. In most cases, it’s not a defect — it’s a dirty filter, a full tank, or air leaks .

1) HEPA: what it is (and why it's relevant)

The EPA describes HEPA as a pleated mechanical filter with a theoretical efficiency of at least 99.97% for particles of 0.3 µm (worst case/MPPS).
For people with allergies, this can help — but only if the system is properly sealed.

2) Fence: the most ignored point

DECO is straightforward: a vacuum cleaner can have very good filters and still emit dust due to air leaks at the joints, brushes, or filter fitting .
In other words, maintenance also includes checking fittings.

3) Simple routine (2 minutes) that maintains performance.

After each "real" use (car or upholstery)

  • empty tank

  • Wash/clean the filter as instructed.

  • Check for hair/hair stuck in the nozzle/brush.

Weekly (frequent use)

  • Clean the tank and dry it thoroughly.

  • Inspect the seals and filter fitting (if it's not "properly closed," it will lose suction).

Monthly

  • Filter cleaning (if the manufacturer allows it)

  • Check battery status/runtime.

4) How do I know when the filter needs to be replaced?

Typical signs:

  • Suction drop even with an empty tank.

  • persistent odor

  • deformed/torn filter

  • “fine dust” returning to the air (in some models)

5) Tips for extending battery life (without complicating things)

  • Avoid storing the battery at a "zero" level for extended periods.

  • Charge when necessary (do not leave it constantly charging if the manufacturer does not recommend it).

  • Use turbo mode only where it makes a difference (carpets, upholstery).
