Whole-machine HEPA filtration and sealed dust containment are frequently praised, especially by pet owners and allergy-focused reviewers. Washable filters are seen as a plus for long-term ownership.

A comparison review cites whole-machine HEPA filtration capturing 99.99% of particles down to 0.3 microns, and multiple reviews suggest dust exposure is minimized by the dirt-ejection/lever emptying design.

Multiple sources describe sealed, HEPA or HEPA-like whole-machine filtration capturing about 99.97% of 0.3-micron particles and passing smoke-style tests, with little noticeable dust leakage.

Filtration is one of the most consistently praised strengths, described as S-class/hospital-grade with multi-stage filtration and strong dust containment for allergy-conscious users.

Anti-Allergen Complete Seal + HEPA filtration is repeatedly highlighted as a major strength for allergy-sensitive homes. Bagless emptying still requires care to avoid dust plumes, and filters need routine cleaning/replacement.

Filtration is a headline strength: reviewers repeatedly mention sealed airflow paths plus HEPA or charcoal/odor filters that help with allergies and pet smells. Bagged dust containment is frequently praised for keeping fine dust from escaping back into the room.

Filtration is a standout: multiple reviews mention HEPA-level or sealed filtration that keeps dust contained and leaves the air feeling cleaner. Some variants add activated charcoal for odor control.

Multiple testers describe the system as well sealed with HEPA-level filtration, helping keep fine dust and allergens contained rather than recirculated.

Filtration is a major strength: multiple sources describe a sealed HEPA system (often cited as 99.9% dust/dander capture) and testing that showed excellent dust containment with minimal particle spikes.

Repeatedly highlighted as having sealed HEPA/anti-allergen filtration that helps keep fine dust and pet dander contained instead of blowing back into the room. This is considered a standout feature for the price tier.

Filtration is repeatedly highlighted as a strong point (HEPA-style capture and reduced dust blowback during use), with washable or long-life filter elements mentioned.

Sealed HEPA filtration is a standout, passing fog/particle tests with little to no visible leakage and earning strong filtration scores. Multiple reviewers call out the allergen system as a meaningful benefit for air quality.

Bagged filtration and the main filter are repeatedly called good for dust containment and allergy-prone homes; one test showed minimal visible exhaust even without a separate exhaust HEPA stage.

Filtration is a standout: multiple reviews highlight HEPA-style bags and filters, strong dust containment, and noticeable allergy relief versus bagless vacuums.

Sealed HEPA-style filtration is a standout in both expert writeups and owner feedback, with several people noting less dust escaping while vacuuming. Washable pre-filters and a large HEPA filter are appreciated for ongoing ownership.

Filtration performance is a highlight: multiple reviews mention HEPA filtration and a sealed or effective system that limits dust escape. Several tests suggest it keeps fine particles well-contained during use.

Dust containment is aided by sealed disposable bags and hands-off emptying, which reviewers with dust sensitivity appreciated compared with manual bin dumping.

Filtration and dust containment are consistently rated strong, with a sealed system and good particle control; HEPA-level filtration is mentioned more often for certain versions or upgrades.

Most reviews describe strong dust containment with a sealed system and effective filtration, sometimes even labeled HEPA whole-machine filtration. One test notes it may not be a true HEPA filter but still performed excellently at keeping fine particles from escaping.

Filtration is repeatedly praised: sealed HEPA-style systems perform well in fog/particle tests and are positioned as allergy-friendly with minimal leakage.

Filtration is a strong point: reviewers call it allergy-friendly, citing HEPA-style containment and a washable lifetime filter that helps capture fine dust. This is a recurring reason it is recommended for people sensitive to dust.

Multiple testers call out a sealed HEPA air path that keeps fine dust and allergens contained, and smoke/leakage style tests are reported as passing well for the price tier.

Filtration/dust containment is widely praised for bagged containment and multi-stage filtering; multiple sources report strong particle containment and cleaner-feeling air after vacuuming.

Filtration is repeatedly praised, including HEPA-style filtration elements and reduced dust blowback. Reviewers frame it as especially beneficial for allergies and cleaner air exhaust.

An extended life filtration system locks in dirt and debris and limits particles blown back into the room, helping improve indoor air quality for households that are sensitive to dust or allergens.

HEPA/bagless filtration is discussed only in an outlier, multi-function Big Green review and does not appear in the core upright extractor-focused reviews.

Dust containment is generally solid, helped by a sealed, bagged dock and replaceable filters. Filters are not washable and need periodic replacement, but most reviewers report clean handling with minimal dust mess.

Fog-based containment tests show the Omni-Glide seals dust and fine particles well without visible leaks, though its easily clogged filter means owners must clean it often to maintain suction.
