Is the filter a true HEPA filter?

No. Envion calls it a HEPA-type filter, which captures many particles but is not certified to true HEPA standards.

How often does the filter need replacing?

The filter is cleanable and rated to last up to 12 months. Wash it as directed and replace it when cleaning no longer restores airflow.

Does the UV light need a new bulb?

Yes. The UV germicidal lamp has a limited life and needs periodic replacement to keep working.

Can I leave it running overnight?

Yes. On its lower speeds it is quiet enough for a bedroom, though the highest setting is loud.

Does it connect to a smart home or app?

No. Controls are on the unit itself, with no Wi-Fi, app or voice assistant support.

What rooms does it suit?

It works best in bedrooms, offices and small living rooms rather than large open-plan spaces.

Our take on the Envion Therapure 230H Air Purifier HEPA-Type Filter UV Germicidal

The Envion Therapure 230H is a tower-style room air purifier that combines a HEPA-type filter, UV germicidal light and a photocatalyst stage. Its filter is cleanable and rated to last up to 12 months, so upkeep is mostly washing rather than buying replacements. It suits bedrooms, offices and small living rooms where a slim unit is wanted. Against rivals at the same level it offers three-stage treatment and low running costs, but it is a HEPA-type rather than true HEPA unit and lacks the smart sensors and auto modes of pricier purifiers.
