Choose the Right Power Supply for Your Air Purifier

Last updated: November 18, 2022 at 16:22 pm

Keeping the air fresh and pure is a necessity nowadays. An efficient air purifier may help keep your home’s environment clean and fresh by removing toxic viruses.

Fortunately, different air purifiers are accessible in the market, but many brands provide vague explanations about their product’s efficiency or make freakish health claims. 

Air purifiers are not a magic bullet to improve your home’s quality, but the perfect air purifier may help you breathe better. Nowadays, it becomes more challenging for us to pick the ideal air purifier power supply.

But there’s no need to worry. Here we have provided a guide to help you choose the ideal air purifier power supply based on your budget and needs. 

What is an Air Purifier, and Why Do We Need It?

An air purifier sanitizes the air containing allergens, toxins, and contaminants. Essential oil diffusers and humidifiers that add particles to indoor air are the polar opposite of such devices. Air purifiers and filters work differently. Air purifiers can also sterilize particles, while the filters only eliminate them. 

Remember that an air purifier is a machine that removes pollutants from the indoor air and improves the air quality in your home, leaving the indoor space clean and contaminant-free. 

An air purifier eliminates contaminants from a room’s air to improve air quality. Dust mites, pet dander, ragweed, dust, pesticides, pollen, second-hand smoke, paint fumes, and mildew are only a few of the toxins that the air purifier filters.

Asthmatics, allergy patients, and anyone with an impaired respiratory system may encounter minor to major health concerns due to these particles. 

An air purifier can purify the air from a broad spectrum of allergens and pollutants, which can be difficult on a person’s health in the long term. The benefits of these devices extend beyond purifying the air from standard pollutants.

It removes smoke

Are you a smoker? Living in a wildfire-prone area? Perhaps you don’t have a well-ventilated kitchen in your home. An air purifier can help eradicate the smoke produced by cooking, forest fires, and tobacco.

Also, air purifiers with a dense activated carbon filter can eliminate the odor caused by any smoke, while a True HEPA filter will filter out any visible smoke particles. 

It captures mold spores.

Mold is a typical issue in most homes, and an air purifier can capture any airborne mold spores before they can reproduce. 

Air purifiers with an activated carbon filter, a True HEPA filter, and ultraviolet light are ideal for mold spore removal. That combination will lower the odor, capture mold spores, and destroy them at their core. 

It traps viruses and bacteria. 

Millions of small virus particles and bacteria can float around your home. Those pathogens and microbes can result in all types of illnesses.

An air purifier can help trap the bacteria as it flows through the system. Nonetheless, that’s not efficient for viruses. To get rid of those, you will like an air purifier with ultraviolet light, which ruins the DNA structure of such viruses, rendering them harmless to your health. 

How Does an Air Purifier Work with Power? 

Electricity runs an air purifier. As with any electric appliance, you must consider the power consumption of air purifiers.

You can run an air purifier 24 hours a day. That sounds quite a lot, especially if you look at it from your electric bill’s point of view.

Fortunately, air purifiers consume a manageable amount of energy. They have a maximum wattage of at least 40W and 200W (even the largest ones max out at 100W). That is for the highest speed settings. Also, you can run an air purifier on a lower 10-to-30-watt stage. 

Many air purifiers consume at least 8 watts to 56 watts. A fridge uses at least three to five times more energy. They ran air purifier magnets with about as much energy as an iPhone charger. 

The voltage is the first thing you must consider when picking or creating a power supply for your air purifier. What voltage does your air purifier needs? That one is quite simple.

If your air purifier needs 9 volts, you need a 9V power supply. If it needs 5 volts, then you need a 5V power supply. On top of that, if your air purifier requires a DC voltage (the most typical), you require a DC output from your power supply. If your air purifier requires AC voltage, you need an AC output. 

In other words, small Purifiers may use the AC power from the wall socket. Meanwhile, large air purifiers need AC adapters or special wiring.

How to Pick the Suitable Power Supply for Your Air Purifier?

An old maxim says, “use the right tool for the job.” However, frequently, there are numerous tools for the job. Thus, how do you know which one to utilize? 

You must understand a few basics to pick the ideal power supply for your air purifier. 

Power Supply Terms

Clarify some confusing terms, but they are essential in choosing the right wall adapter power supply. Linear power supplies versus AC-to-DC switching power supplies are sometimes misleading terms to those people who are not familiar with them.

A switching power supply takes an AC input but filters and rectifies it into DC first. It’s converted back into AC at a high switching frequency and steps down the voltage with a transformer. It’s fixed and filtered into a DC output. 

On the other hand, linear power supplies take an AC input, step down the voltage with a transfer, then rectify and filter the input into a DC output.

The main modification between these two is that they enable various components you can use. On the other hand, the linear power supply is less efficient and utilizes a heavier and bigger transformer and bigger filter components.

The switching power supply indicates higher efficiency because of the high switching frequency, allowing it to utilize a smaller, less expensive high-frequency transformer and lighter, less expensive filter components. Switching power supplies have more overall components and thus usually are pretty costly. 

Power Supply Current

The air purifier you like to power will require a particular amount of current. If you purchase one, it must indicate how much current it requires somewhere in the technical documentation or by the power connector. 

For instance, your device requires 1 ampere. That indicates you should pick a power supply that can provide at least a minimum of 1 ampere. 


Often, a power supply offers you several watts. Watt is only the voltage multiplied by the current. Therefore, if you have a 5-volt power supply that can provide a 1A of current, you will need a 5W power supply.

If the power supplies say 12V and 100W, you can figure out the maximum current by a basic calculation. 

Current equals the watt divided by the voltage. Thus, that’s 100/12 = 8.3A. 

Power Supply Voltage 

Another thing you need to keep in mind when buying a power supply is the voltage. That one is quite basic.

If your air purifier requires 9V, you need a 9V power supply. If it needs 5V, then you need a 5V power supply. 

On top of that, if your device requires a DC voltage, you need a DC output from another power supply. If your air purifier requires an AC voltage, you will need an AC output. 

Tips and Tricks for Choosing an Air Purifier Power Supply

You will find different uses of power in your daily life. Therefore, the demand for power product accessories like chargers, adapters, and LED drivers from Prowin Power is increasing.

Nonetheless, even though those products are accessible in the market at a high quality, people seldom talk about choosing the ideal power supply unit to power their air purifier. Those result in misuse, thus increasing the need for replacement.

Here are some tips and tricks for picking the best power supply unit for your air purifier. 

Ideal wattage for your system when selecting a power supply unit 

The initial step is to consider different ways to pick power supply wattage for your system. Each air purifier has particular power needs. When choosing, remember the minimum wattage rating for it.

You can utilize a decent power supply calculator to offer you an estimated figure when in doubt. The only drawback of picking too low wattage indicates your device will need more juice to power up, while extremely high watts might suggest you cannot use them. 

Consider wall outlets

You draw substantial power from the electrical grid when you plug an air purifier into the wall outlet. Remember that you can use a wall outlet to handle the big load of most appliances.

They also lessen tripping hazards, which are risky if something is wrong with either the plug or the outlet. Electrical appliances, generally, are better off plugged into a wall outlet. Furthermore, electrical appliances require a consistent flow of electricity that can warm cables as the day wears on. 

That is why it isn’t easy to plug in appliances in wet regions. That application could cause a power strip to overheat or trip the circuit breaker. Make sure you utilize a dedicated outlet when utilizing such machines. 

Verify the wattage.

Before connecting an extension cord to your air purifier, it’s wise to confirm its wattage to ensure you’re not straining the cable. You can do this by looking at the label of the extension cord.

Unless batteries power your air purifier, plug it into an electrical outlet. Plug-in air purifier versions have a fixed power connection attached to an electrical outlet while the devices operate. 

Choose the ideal extension cords.

When choosing an extension cord for your air purifier, there are some considerations you must pay attention to. 

Lower resistance and boost overall efficiency by using the shortest cord possible. The energy required to run the appliance increases when using an air purifier with an extension cord. That’s proportion to the extension cord’s length. Also, longer wires are more likely to become tangled, raising the risk of tripping over them. 

Choose an extension cable that is compatible with plugs having three prongs. Hence, the electricity is grounded, and no one will get an electrical shock. 

Avoid overloading the extension cables to lower the overheating and catching fire risk. 

Consider the length of the air purifier from the wall. 

For your air purifier to work properly, they need a massive space to draw in air and expel it into the room. When pressed against the wall, it can’t take in as much air as it would. It’s not simple to offer a conclusive solution to where you should place it. 

Place your air purifier in a good area for it to function properly. It will help if you consider other things, like positioning it near the source of pollution or ensuring it doesn’t cause problems with other equipment. 

If you have a portable air cleaner that you move from room to room, take it wherever you go. 

Final Thoughts on Air Purifier Power Adapter

To sum up, remember that you don’t need to put in a massive effort to create the power supply requirements you need for your air purifier if you use help from manufacturers and accessible resources.

Before any selection assessment, it is critical to determine your requirements. There’s a major difference between choosing what you need and what you’d want.
