My neighbor convinced myself and others to roll with HEPA filters

When my neighbor was telling myself and others that I should invest in HEPA filters, I completely laughed at him.

She seemed extreme plus asked why I was even laughing.

I told myself and others that there were all kinds of benefits to using HEPA filters. I told him I was laughing because all air filters are basically the same plus the more overpriced a singles are just a scam to get your money. She told myself and others she begged to differ. She told myself and others that HEPA filters pull 99.9% of the contaminants from the air. When I asked him how she knew they could pull that much. I also asked him why they couldn’t pull 100% of the contaminants, what was up with that .1%? She said it would be impossible to pull all the contaminants even though it was absolutely a little less than 99.9%. I felt like I couldn’t trust the HEPA filters for the simple fact that they boasted they could pull so several contaminants from the air, but my neighbor said I had to try them to see for myself. She even told myself and others she would spend my savings for myself and others to have a single HEPA filter. She wasn’t lying too, she got myself and others a HEPA filter the next day plus I installed it. I told him it wouldn’t make much of a difference. Well, she even had a gadget that measures the air quality. She sampled the air quality in my home plus had myself and others write down the number, so I could entirely see how much my air quality would improve. About various weeks later, she worked on the air quality again in my home plus it was phenomenal. I didn’t even need that gadget to tell me, my neighbor was right. I felt good having cleaner breathing air plus I decided I would invest in HEPA filters moving forward.
