    • Our take on the BreatheSmart 35i HEPA Filter

    This is a replacement H13 medical-grade HEPA filter made for the Alen BreatheSmart 35i air purifier. Alen sells it in two versions so you can match filtration to your environment: a standard HEPA option and a carbon-enhanced option for odors and gases. It is a consumable, not an upgrade, so its value depends on how much particulate and odor load your room carries. Owners of the 35i rate it around 3.9 out of 5, with praise for filtration and complaints centered on fit and longevity.

    • FiltrationPraisedOwners say dust and pollen levels in the room drop after fitting a fresh filter.
    • LifespanCriticisedSeveral owners feel the filter loads up faster than the rated interval suggests.
    • FitMixedSome report the filter seats cleanly; others say it sits loosely in the housing.

    Questions and answers

    Is this a genuine H13 HEPA filter?
    Yes. Alen describes it as medical-grade H13 HEPA media, which captures a higher share of fine particles than standard HEPA-type filters.
    Which version should I pick?
    Choose the standard HEPA version for dust, pollen and pet dander. Choose the carbon-enhanced version if you also want help with cooking, pet or smoke odors.
    How often does it need replacing?
    Alen's guidance depends on runtime and air quality; heavy use in a smoky or pet-heavy room means more frequent changes. The purifier's filter indicator is the practical guide.
    Does it fit other Alen models?
    No. It is made for the BreatheSmart 35i. Other BreatheSmart models take different filter sizes.
    Is it washable?
    No. HEPA media is not washable; washing damages the fibers. Replace it when airflow drops or the indicator calls for it.
    Where is the BreatheSmart 35i HEPA Filter cheapest?
    At Alen | Store, for $54.00, as of our latest check.
    What do buyers say about the BreatheSmart 35i HEPA Filter?
    Rated 3.9 out of 5 from 12 ratings.
