Hi Sally, I am sure there would be someone in your area who would rent out Ironising filters, and I have to tell you, they are amazing at getting rid of unwanted odours. The Hepa filtration scrubs everything from the air.
We have a Whirlpool Whispure 1000 built into the cottage air circulation system. We don't have an exhaust fan in the living area but guests can cook eggs and bacon for themselves at 8.00am, be gone by 9.00 and by 9.30 there is absolutely no evidence of cooking in the cottage. It's great if you strike a smoker as well, within an hour or so it will have the air cleaned up again.
Next time you strike this get onto someone in your area who rents them out......it is far cheaper and easier than having to re-paint or wash everything.
Just make sure you don't get the cheaper Ozone filter...It is well documented now that Ozone filters can create, or exacerbate lung problems and some authorities around the world are banning their use.
A look on Ebay or Craigslist or similar I am sure would offer ironising filters for sale at a reasonable price.....It's a good investment!
Here is the link to a review on the current model that has replaced the one we have!

Good luck and keep this in mind Sally!
