A fully sealed HEPA system captures 99.97 percent of particles down to 0.3 microns and has repeatedly passed smoke tests, making the V11 a strong choice for allergy-sensitive households.

Multi-layer HEPA-style filtration plus the sealed bag dock are repeatedly framed as excellent for allergies and pet dander. Several sources cite very high particle-capture claims, though most reviewers rely on observed dust containment rather than lab verification.

Repeatedly praised: sealed systems plus HEPA-style filtration are reported to contain dust well and pass fog/smoke-style tests in multiple reviews.

Multiple sources describe the V10 as having sealed, high‑efficiency filtration (often quoted as capturing 99.97% of particles down to 0.3 microns), helping contain fine dust and allergens.

A fully sealed system with a HEPA filter captures fine dust effectively and passes fog-style leak tests, making the Digital Slim a strong option for allergy-sensitive homes.

A sealed HEPA anti-allergen system keeps captured dust from leaking back into the room, a feature still rare among cordless vacuums at this price.

A sealed whole-machine HEPA system is repeatedly credited with keeping fine dust/allergens contained (often cited down to ~0.3 microns) and passing smoke/leak tests, making it a strong option for allergy-conscious homes.

Filtration and dust containment are a strong point, with a sealed system and HEPA filtration performing well in fog/particle tests. Reviewers often cite it as a good option for allergy-conscious homes.

A sealed system with lifetime HEPA filtration helps the NV752 capture fine dust and allergens and keep them inside the canister, a benefit confirmed in smoke leak style tests and appreciated by allergy conscious owners.

Its fully sealed HEPA system keeps dust and allergens inside the vacuum so exhaust air stays clean while you clean.

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.

A sealed system and HEPA filtration give the PowerDetect perfect or near-perfect filtration scores in testing, making it a strong choice for allergy conscious homes.

Reviews consistently point to strong whole-machine filtration, commonly cited as capturing 99.99% of particles down to 0.3 microns (with some variants like Absolute advertised with even finer HEPA capture), and washable filters help maintain dust control though drying time is about a day.
