Hello LoveAO
I'm sorry to hear about your Mum's diagnosis but it's good to know that her surgery was successful. I do hope that she's recovered well from it. 

It's understandable that you want to keep Mum as safe as possible during her chemo, particularly during this difficult time with Covid19. It sounds like you've got lots of things already covered. 
I'm unsure about air purifiers but hopefully if any of our members here have used them then will post to share their experiences with you. 

If you'd like to have a chat with our team of nurses about your concerns about keeping Mum as safe as possible then you're welcome to give them a call. They're available Monday to Friday 9am to 5pm on 0808 800 4040. 

Best wishes,

Hello LoveAO,

                     l assume you mean to use the air purifier to scrub the air inside the house and attempt to filter out any airborne virus,In order to do that you would need a very sealed house and an awful lot of purification power in order to put all the volume of air through the filter resulting in a constant cycle.Personally l think you are approaching  this the wrong way insomuch that dust particles remain suspended for up to 36 hours in a still environment,and that dust particles measured in small microns can play host to virus piggybacking upon them,and it is these that can be breathed into the farthest recesses of your lungs.A number of years ago  l ran trials for rentokil for industrial ionisers in the farming industry,which gave a picture of what was happening. A good airflow never allow these particles to remain suspended since they are carried along in the airflow.Good ventililation also points to a colder background as we approach winter,and a chemo patient will feel the cold.

                                                                       So the option is a very powerful purifier (s) that cover the house or accompany the patient to whatever room they occupy, possibly an ioniser to settle fine dust,or good ventilation ensuring the patient is kept warm if the room is not,layers of clothes spring to mind.Fresh oxygenated air would be better than stale for a patient under stress experiencing laboured breathing.

                                                                                                 l  had career in intensive livestock production,and the biggest killer was the stress bought on by inadequate ventilation,being the trigger for all manner of ills to seize their opportunity.Never saw pnuemonia bought on by a cold draughtfree environment,but witnessed far too much bought on by insufficient ventilation and warm humid air.The message that emerged  waqs that in insufficient ventilation you need to capture the dust from the environment,the better option was to increase airflow without creating draught

                                                                                                                     Food for thought and l hope your mum continues to make good progress,
                                                    David
