HEPA Vacuum Cleaners
Few people think about their vacuum cleaners as sources of air pollution in their homes. Yet frequently, the air people breathe after vacuuming is dirtier than it was before they vacuumed!
Many vacuum cleaners pick up the larger particles of dirt, so that your home or carpet looks clean. But, the smaller particles may not be retained by the vacuum cleaner's filter. These small particles are shot out in the exhaust air, aggravating allergies and redistributing dust and other allergens throughout your home.
The problem with this scenario is that the smallest particles are the most dangerous to allergy and asthma sufferers. The smallest particles are more dangerous to lung tissue because they can penetrate deeper. These irritants can then trigger another attack. Of even greater concern, these microscopic particles can float for hours before settling down. Anyone in the room is breathing them in.
This is where HEPA vacuums come in. Scientific studies show that HEPA vacuums are excellent for containing dirt and allergen particles. The newest HEPA vacuums are well engineered with many features that combine user friendliness with superior suction power.
As a result, HEPA vacuum cleaners are becoming a popular appliance in many homes to help control pet dander, pollen, molds, spores and other catalysts of allergies and asthma. A true HEPA vacuum is outfitted with industry-standard HEPA filters that prevent almost all particles from re-entering the room through the vacuum's exhaust.
There are many varieties of HEPA vacuums available, including upright models, canister models and even HEPA central vac systems for the whole home.
Here are the key features to look for when shopping:
- HEPA - not "HEPA-like" - filter
- Lightweight, sealed system with rubber gaskets to prevent leakage
- Two-fan suction motor to pull more dirt and allergens
- Easy controls, adjustable suction control and good manoeuverability

- Hygienic dust bags (as opposed to brands without bags)
- Excellent warranty
- Rotating power nozzle on canister models
