While some people often grumble about the fact that air pumps don’t really last for a long time and often go bad rather quickly, the good news on the other hand is that they aren’t really expensive. Most air pumps will cost you between $25 to $55 with the $30s being the most common price range. Hardly will you ever exceed the $55 price point though you are likely to find some priced even lower than $25. Air pumps aren’t an expensive lot, plus when you buy them from Amazon, you are bound to get good discounts even on their regular low price point.
