If you use a humidifier to help keep your humidity at recommended levels of 30% to 40%, some models do require you to replace the filters from time and time. There are different types of humidifier models and different types of filters. Some operate with HEPA filters, others have wick filters, and still, others have filter cartridges.
First, when purchasing a replacement filter, no matter what model you have, most humidifier manufacturers will tell you to stay away from “aftermarket” or generic filters and buy the recommended filters. While the generic filters may be cheaper, they may not last as long or even work in your unit. For instance, if you have a Holmes humidifier, you should purchase a Holmes filter.
Filters are used in humidifiers to help keep the moisture your humidifier puts out clean and free of pollutants you don’t need in the air. Some also remove tap-water elements from carbon-based filters. While the humidifier pulls in air and returns it to the air (either in a cold or warm mist), the filter blocks dust and air particles. Therefore, it is essential to clean or replace your filters from time to time.
Humidifier filters should be changed every one to three months. Humidifiers have to work harder if a filter is not changed, which can damage the humidifier and even use more energy costing you money. It can also put dirty elements into the air because the filters aren’t working properly.
Some reasons a filter may have to be changed can be too much smoke in a room, a lot of animal dander, or if you live in a dusty environment. You should follow the manufacturer’s instructions on cleaning, dusting, or washing any air filters, if they offer that option before you replace them.
Hard water can also cause a humidifier filter to have a shorter life so if you know your water isn’t at the greatest of levels; you can use bottled water if the manufacturer says it’s acceptable to do so.
If you follow through with good hand dusting of your filters, they will probably last the recommended three months, but sometimes by cleaning them, you can extend that life for one or two months. For convenience, look for humidifiers that have replacement filters with the original purchase of the humidifier or buy replacements at the time you buy the humidifier.
Before you buy your replacement filter, make sure you write down the manufacturer name and model of your humidifier and when you go to the hardware store, discount retail store or home and garden center, make sure you buy the correct filter.
If you can’t find the filter for your exact make and model of a humidifier, look at the operating manual that came with your humidifier and see if they offer a customer service telephone number that can either connect you to the company’s sales department or find out where you can buy their replacement filters in your area.
To ensure your humidifier operates well and is effective, match the filter to the model and avoid aftermarket or generic models. You can also find replacement filters on many online sites by just typing “humidifier replacement filters” in any search engine.
