Our Top Air Compressor Filter Dryer Recommendations
An air compressor filter dryer is used to clean your compressor. Having a dryer also means a lesser chance of forming rust. This helps keep your compressor operating in good condition for a long time. Below is a list of some of the best air compressor filter dryers you can get.
Best Air Compressor Filter Dryer Overall: Nanpu DFR-03 Npt Air Drying System
The NANPU DFR-03 NPT Air Drying System is one of the best filter dryers you can get for your air compressor. This double-air filter is made to remove water and other liquids as well as particles from your compressor.
A double filter generally cleans better compared to a single filter. This NANPU filter dryer also has a self-relieving pressure regulator for adjusting outlet pressure, so you won’t have to worry about maintaining the right pressure. This makes this air-drying filter system one of the most popular ones on this list.
The calibration for this dryer filter follows the maximum flow requirement, and you just need to assemble it properly for use. This air drying system can function as an air filter, lubricator, and regulator, reducing your need for spending on other accessories.
It has a port size of ⅜ inch, so it will only fit with compressors with the same port size. So make sure you check your port size or get an adapter.
The pressure adjustment on this air-drying system is easy to use. Just pull up the knob of the pressure gauge and rotate it. Clockwise to increase pressure and counterclockwise to decrease.
The easy pressure adjustment is mostly present in most of the dryer filters in this list, so you will easily operate them. This feature is common for highly popular filters, and not having it is usually a dealbreaker for some people.
When it comes to drainage, the drainage column automatically excretes when there is no pressure. It also closes when air is flowing. However, you still have to drain it from time to time for proper dehumidification.
Overall, we put the NANPU DFR Air Drying System as the best overall with all the features and downsides in mind. It gives you everything you need for a dryer filter and some extra. Some of the downsides we can find for it is that its size is limited, so you might have trouble fitting it in some compressors.
Pros
- Double filter and self-relieving pressure makes it effective in filtering
- Adjusting the pressure is easy and simple
- Oil-free, so you won’t worry about maintenance for a long time
Cons

Features to Consider for Air Compressor Filter Dryer
Choosing the best air compressor filter dryer comes down to how effectively it can filter out and dry the air compressor.
Compressor Type
The type of compressor you use decides what filter is best for you. There are three main types of air compressors: centrifugal, reciprocating, and rotary screws. Most filter dryers will have descriptions of what air compressor they are compatible with.
When choosing a filter dryer, it depends on compatibility. Hence, you should check with the manufacturer to know if your compressor model has recommended filter dryers.
Load Capacity
The best air compressor for you should be able to handle your air compressor’s load. Otherwise, it won’t last while you are working on an application, so you have to empty it out more frequently.
The NANPU Air Drying System is your best option as it can easily handle compressors with huge load capacity.
