undefined store has been out of filters for weeks

I am not sure what is going on with the Heating, Ventilation plus A/C stores lately, then i have numerous heating plus a/c company stores close to me, plus neither of them have our number one kind of air filter, which is the HEPA air filter, however although, even if I was less picky plus decided to go for a lesser quality filter, they are out of most of those too! All they have left at the Heating, Ventilation plus A/C suppliers is the actually cheap generic filters, which there is no way I am going to risk damaging our Heating, Ventilation plus A/C unit by using those disappointing things; When I first observed the store was out of stock, I didn’t actually think that much of it, however, when I returned a week later, plus they were still out of stock, that is when I was beginning to get exasperated.

I even went to the other a/c store, just to see if they had any of the filters in stock, which of course they didn’t, or otherwise I wouldn’t be complaining about this right now.

I am just ecstatic that I still had one extra air filter left over, otherwise I don’t think what I would do. I have only had the new air filter in for a week, plus I usually change out our filters every 3 weeks, so hopefully in the next numerous weeks, the stores will have the filters back in stock. If they are still not in stock, I might have to look into ordering online, plus hoping that will do the trick.
