@trendless One of my clients is moving into a small ground floor suite & has asked me to source & purchase air filtration unit for her 2 rooms suite & a comfortable reusable mask. She has budget of $1500 for air filtration unit & $500 for mask(and extra filters). I don't know which ones may be best for her & am seeking some advice on possible products. Can you please help or point me to someone who can advise on possible products that would be best for my elderly & highly immune compromised client?
