Hoover Replacement Filter for H-Purifier 500 and 700

Hoover U98 H-Trifilter Replacement Filter for H-Purifier 500 & 700

Keeping your air purifier running smoothly starts with the right filter. This three-layer replacement from Hoover works with their H-Purifier 500 and 700 models, using a mix of HEPA and activated carbon layers. The cylindrical design isn’t just for looks—it lets air move more freely than flat filters, which can help your unit work a bit more efficiently.

You’ll get 99.97% particle capture down to 0.3 microns. That covers most common allergens, dust, and even some cooking smells thanks to the carbon layer. Installation instructions are printed on the filter itself, though a few users mention needing a minute to align it properly. Once locked in, it’s designed to stay put without shifting.

At just over a kilogram, the compact size fits neatly into the purifier’s housing. No batteries or tools are needed—just slide out the old filter and click this one into place. Some note it lasts longer than third-party alternatives, which could save hassle over time.

Reviews lean positive, with a 4.5-star average across 47 ratings. Buyers in smoke-heavy households praise its impact on air quality, while others call it a straightforward swap. A handful found the locking mechanism finicky initially but say it settles after a few tries.

Priced around £57, it’s mid-range for branded replacements. If you’re sticking with Hoover’s system, this keeps things consistent without guesswork. Just remember to check your model number—it’s only compatible with the 500 and 700 series.

Noise levels and room size specs aren’t listed here—those depend on your purifier unit itself. But for maintenance, this does what it’s meant to: replace spent filters without complicating the process.
