I honestly should check the sales that our local hardware store has more often. I recently missed a sale on HEPA air filters and I could not know it! This was something that does not happen often. Having a sale on HEPA air filters is not something to be missed. HEPA air filters are pretty costly as it is, so when and if you find them on sale it is love the deal of a lifetime. If I had checked the sales at our local hardware store I could have taken fortune of this good sale. I am hoping that maybe they hardware store will have another sale on HEPA air filters sometime in the next coming months. I will for sure be keeping an eye out to see if the HEPA air filters go on sale again. I won’t miss out the next time. As it is, I do buy the HEPA air filters at their normal price because I found that HEPA air filters are the only air filters that go well in our central heating and a/c system unit. HEPA air filters only have to be changed every few months and also HEPA air filters make for good air quality in our home. The high cost is well worth it and easily in the long term saves me money on buying air filters because I do not have to buy them as often. But I am seriously kicking myself that I missed this honestly good sale on the HEPA air filters at our local hardware store! Live and learn as they say and I will be paying more attention in future.
