My canned air gets cold and weak before I finish cleaning the filters. Is there a better way to use it, or should I switch to an electric duster? What are the downsides?
Why does canned air freeze up while I'm cleaning my PC, and what else can I use?

The can cools as the propellant is released, so a long blast can leave it cold and low on pressure. Use short bursts and give it time to warm up between them. Keep it upright and don't shake it, since tilting it can spray liquid propellant onto parts.

An electric duster is a good replacement if you're tired of buying cans. Plug-in models can be powerful, but they're often loud and cost more upfront. Rechargeable ones are more portable, though you have a battery to charge and eventually replace.
Shut down and unplug the PC first. Hold the fan blades still while blowing them out, and start with the nozzle farther away if the airflow is strong. Take the machine somewhere you don't mind dust blowing around.

Good to know about the noise. Is there a reason to pick a plug-in one over rechargeable?

A plug-in model doesn't need charging, which can be handy for longer sessions. Rechargeable is easier to carry around, but strength and runtime depend on the model.

For dust stuck to a removable filter, take the filter out and loosen it with a soft brush before blowing it off. You might not need much air at all. Check how dirty the filters actually get and clean them as needed rather than sticking to a fixed schedule.

A regular air compressor is another option if you already own one. Use a suitable moisture filter and a pressure regulator, and hold the fans still. It's a bulkier setup than an electric duster, so probably not worth buying just for an occasional PC clean.

Let it warm naturally rather than trying to heat the can. If it still has propellant, getting cold doesn't necessarily mean it's empty.
