Shop Purifier Filters

Serious odour and VOC control for your Smart Air SA700. Each filter contains 750g of granular activated carbon, 1.5kg in total when both are installed, which is more real carbon than any other purifier setup we sell. Activated carbon adsorbs gases that HEPA filters can't touch: VOCs from paint, new furniture and cleaning products, plus cooking smells, pet odours and woodsmoke. The carbon filters fit behind the SA700's HEPA filters on both sides and can be added or removed any time. Sold as a pack of two.

Upgrade your Smart Air SA700 to the highest grade of HEPA filtration available. These H14 filters capture at least 99.995% of airborne particles per pass, the same standard used in hospitals, operating theatres and cleanrooms, and are independently certified to EN1822. With H14 filters installed, the SA700 delivers a CADR of 490m³/h, covering spaces up to 60m², and the denser media means they last longer too: around 18 months running 8 hours a day.

The right choice for clinical settings, high-risk households, and anyone who wants maximum single-pass capture. Sold as a pack of two, replacing both sides at once.

A note on labelling: These filters were originally graded H13. Smart Air has since had them independently tested and certified to the higher H14 standard (EN1822), but current stock still carries the original H13 label printed on the filter frame. If your filters arrive labelled H13, they are the same filters, certified H14.
