HEPA Filters and Anti-Allergen Complete Seal Technology

There are some vacuums that have a major flaw: they pollute your air with the dust and dirt they remove. When you suffer from certain conditions such as asthma or allergies, this is one of the nightmare scenarios you are trying your best to avoid. The dust and allergens in the air could trigger reactions, thus making you run away from vacuum cleaners.

With these two Shark models, that’s not a worry. They are both equipped with HEPA filters and anti-allergen complete seal technology. Consequently, most of the dust and allergens in the air will not make it back into the household air, as they will be trapped inside the vacuum. As a result, your nasal tract will be safe. In addition to this, the HEPA filters are washable as well.

The attachment genie helps a lot with hard floor cleaning, and it even includes a microfiber pad to smoothly remove the debris.

Both of these models have a caddy canister that allows you to use the motorized brush to collect the dirt in the extended vacuuming period. So, this three-in-one vacuum is sent to a portable box that has a straw floor and uses the caddy canister support.

Moreover, you can keep all the attachments you like in the caddy, so that they’re much easier to reach.
