I like it when something expensive lasts for a long time.
I paid more money than I would like to admit buying a peppermint scented holiday candle last year, but it actually survived for three months.
Ounce for ounce, it was a fairly economical candle from how slow the wick burned. It had one of those wood wicks inside that will smolder at a low temperature if you keep them trimmed low in between uses. You have to make sure you allow the candle to cool and harden again before trying to trim the wood wick, otherwise you could dislodge the wick altogether and damage the candle considerably. But after using these candles twice now, I think I understand how to keep the wicks alive for as long as possible. If I can find these candles at a discounted price, I have no reason to ever buy anything else. My air purifier is much the same way. It’s a hardy machine that has been working diligently for me over the past three years. One of the nicest things about these air purifiers are the HEPA filters inside. Not only do the HEPA filters pull out 99% of all airborne contaminants, but they also last up to six months of daily usage. My air conditioner filters only last four to six weeks even when I buy the expensive ones. And whenever I have an air purifier running in my house, it cuts down on the amount of dust that gets caught in my HVAC filter in the first place, making that last longer as well.
