Bathroom extraction fan

[lknights1987]

Hi all,

I have just bought a 2 bed first floor flat with loft access (it’s ex council flat) there is no extraction fan fitted in the bathroom. The only thing that there is is an air vent.

The bathroom is about 7ft x 7ft so quite small.

Is it ok to remove air vent and install an extractor in its place?

Also in the kitchen I have a hood but no where for the air to go other then to the ceiling once hood is turned on. What is the best way to extract the hot air when cooking? Even when the windows are wide open the kitchen is like a steam room!

1. perfectly OK to remove the vent and fit fan.
2. fit ducting to cooker hood, vent to outside. or fit an independent fan in outside wall.

We rented a new build flat afew years ago and the kitchenette was in the middle (no window) the cooker hood fan had absolutely no ducting at all.
It just sucked air up and blow it out the top
This was a brand spanking new build flats built around the mid 2000s
Every single flat had the same issue.
Oh and the bathroom had no window and no fan either just an ip drum light...

This can be quite common, some extractors come with an additional filter that supposed to take out the free radicals (particles/smells from cooker fumes) and reintroduce the "cleaner" air back into the environment. Bit like a C.A.T on a car. Personally I much prefer the fumes to be vented outside and aid towards global warming.

Just as a bit of additional info. Bathrooms have Zones and depending on where the extractor fan is fitted depends on the IP Rating the extractor fan needs to have.
Where about, relative to the bath, is the extractor fan being fitted? Please give dimensions.
Also the wiring for the fan will have to have RCD protection. Does you consumer unit have an RCD?
This work may fall under Part P.

Just to make it simpler for you mate. Below is a screen shot of the different zones.
What zone is your extractor fan going in?

I have seen these type of hoods but believe me this hood had no such filters , it was quite literally sucking air in and blowing it straight out the top....

Ideally the cooker hood should be vented externally
In your case possibly best through the roof via a ducting and a roof vent tile
I have known of them to be just ducted into the attic space most roofs have vent tiles built in for purpose of the timbers to breath, so at least there was extraction to the outside of sorts but its own vent tile or direct through the kitchen wall may be your correct action
Other than that,the internal carbon filters should reduce vapours

If you can afford it.. the best solution would be a MVHR system. This would extract the moist and smelly air from the bathroom and kitchen and send it outside... at the same time bringing in fresh air from outside... but in the middle is a heat exchanger, so it's thermally efficient. That's what I'd be doing if it was my flat !

Last few kitchens I’ve had have been installed with cooker hoods with built in filters that just recirculate with no outside vent. No issues at all. Wife does get upset occasionally with the Saturday morning fry up Probably need to make a call dependent on how much smelly, smokey cooking you’ll be doing.

And dishwasher the filters !

I have washed the outer metallic gauze filters in a dishwasher but the extractor hoods also contain an internal carbon filter cartridge which obviously has to be replaced. Check manufacturers instructions!
