Low-chemical antimicrobial fogging in London
Get your rooms treated and fresh before you redecorate or move back in.
From £380, depending on the size of your home
In short
Simply Filtered provides low-chemical mould treatment across London inside the M25. It helps reduce mould spores and bacteria in the air and on surfaces after mould, a leak or a clean-up. We use hypochlorous acid (HOCl), a gentle, pH-neutral disinfectant, applied as a fine dry mist. Duncan Ridley carries out every treatment himself, and the home needs to be empty of people and pets for 3 to 4 hours. Treatment is a supportive hygiene step: it doesn't fix the cause of mould.
Sound familiar?
The work is done, but the room doesn't feel finished.
- “It's dried out, but it still smells musty.”
- “The mould's been cleaned off and I want the room treated before I paint.”
- “We want to move back in, but is it actually clean?”
- “The tenant has moved out and I want the flat fresh for the next one.”
- “I don't want the house full of harsh chemicals, especially with the kids.”
Treatment works best at exactly this point: after the cause is fixed and any damaged material has come out, and before the paint goes on or the furniture comes back.
See how treatment is pricedWhat we use, and why
A gentler approach to a mould problem.
Hypochlorous acid is a mild disinfectant, the same substance your own immune system makes to fight infection. It's widely used in food production and healthcare, and it's pH neutral. It doesn't leave heavy chemical residues or strong smells: there's just a very faint hint of chlorine that soon fades.
We apply it with a nebuliser, which turns it into an ultra-fine dry mist that reaches across rooms and into corners that are hard to treat by hand.
How it fits together
Treatment is one part of doing the job properly.
Remove
Mould-damaged materials are cut out under controlled conditions, with air filtration running.
Dry
The building is dried out properly, with moisture readings checked before moving on.
Treat
Rooms are misted with HOCl while empty.
Clean
Surfaces are deep-cleaned with plant-based products to remove the dust where mould residues collect.
We carry out the treatment ourselves, and can arrange the other steps through trusted partners, depending on what your home needs.
We check humidity before and after treatment, so you can see the room is left in good condition.
When treatment makes sense
Treatment is the final step, not the first one.
Treatment makes sense once the cause of the mould or moisture has been dealt with. Booked too early, it treats a room that's still getting damp, and the mould has every reason to come back.
A good time to treat
- After mould has been cleaned off and the cause has been fixed
- After a leak or flood, once drying and any strip-out are finished
- Between tenants, before the next one moves in
- Before you redecorate a room that's had mould
Not the right step yet
- You don't know why the mould keeps coming back: start with a mould survey
- Water is still getting in: get the leak found and fixed first
- Walls or floors are still wet: they need drying before treatment
Two formulations
Choose how your rooms smell afterwards.
Formulation one
Pine Fresh
A clean, lightly fragranced finish, for when you'd like the room to smell fresh as well as be treated.
Formulation two
Odourless
No added scent. A good choice if anyone in your home is sensitive to fragrances, or you'd rather the room smelled of nothing at all.
Tell us which you'd prefer when you ask for your price. Both are applied the same way.

Questions
Questions about antimicrobial fogging.
Will fogging get rid of my mould?
Fogging reduces mould spores in the air and on surfaces. It doesn't fix whatever is causing the mould, and it isn't guaranteed to stop mould coming back.
If you don't yet know why the mould keeps returning, start with a mould survey so the cause gets dealt with first.
How long do I need to stay out of the house?
3 to 4 hours. Your home needs to be empty of people and pets for that time, so most people plan a morning or an afternoon out.
How much does antimicrobial fogging cost?
Fogging starts from £380. The price depends on the size of your home and how many areas need treating, and your free quote gives you the exact figure.
Is fogging covered by home insurance?
Fogging is often covered as part of a home insurance claim. Check with your insurer.
Will my home smell afterwards?
That's your choice. Pine Fresh leaves a clean, light fragrance. Odourless adds no scent at all.
Do I need a mould survey before fogging?
Not if you already know the cause and it's been fixed, for example after a leak that's been repaired and dried out. If the mould keeps coming back and nobody knows why, a mould survey first means you aren't fogging a room that will keep getting damp.
