Cheap Air Purifiers Buying Guide

There is a lot that you are going to want to think about when you are looking at buying an air purifier, especially if you don’t want to spend a lot. You should ensure that you know what models are available, along with some of the top features that you might want to look at. The more you know about the models and what to consider, and what to avoid, the decision can be much easier for you, so keep reading on to find out more.

Top Features to Look for in the Best Cheap Air Purifier

You always want to know what some of the best features will be when searching for the perfect air purifier for you. There are so many options that might become confusing, and you might need some help, which is when the features come into play. Here are a few of the top ones to look at, such as:

  • Multi-stage air purification – You want to think about getting a model with a multiple-stage air purification system, which should include a pre-filter. This will help get all of the small or large particles and pollutants lingering in the air. Think about going for one that has the True HEPA filtration system along with one that uses activated carbon to get rid of any lingering odors.
  • Frequency of filter replacements – Also, you want to consider how often you will have to change out the filters with new ones. This will help the air be cleaner since the dirt and debris will collect in the filters, which means that the air isn’t always the healthiest. Ensure that you are looking at how often they need to be replaced and how much the filters will cost you.
  • Maximum room area coverage – The final feature you need to consider is just how much square footage the device would handle. This might be the most important thing to consider since you want it to cover the entire area. If you want it to cover one room, then think about how big that room is and then find the device that can handle it.

These are just some of the main features you are going to want to think about, and you should consider using them to help you with your decision. The more you know about the features, the more you can determine which one would be important to you and which one you can do without.


  • How many hours is the most I should be running my device daily?

You should run it around 12 hours a day, but you can also run it all day if you are home. If you aren’t home, consider turning it off while you are out and then turning it back on to ensure that you are conserving energy. However, for those at home all day, they can be run all day, including sleeping if required.

  • Where is the right location to place my device?

Many people have a question about where the device should be placed, and it depends on the size and type of machine you have. You want to make sure that it isn’t placed fully in the corner, and it should be able to pull in some of the air around it. You can also place these on your desk or even a bookshelf, provided the vents are not blocked.

  • How often should I change out the filters?

This really depends on the type of filter you are using, but most of them need to be changed out at least 1 time every year. If you have the washable filters, then you should wash them when the air feels as if it isn’t being cleaned anymore. Ensure that you are noticing any change in air quality to replace the filters, so ensure you have one handy.

  • How do I know what size machine I should get for my bedroom?

If you are going to place one of these air purifiers in your bedroom, you need to be aware of the square footage. This will help you choose the best option from the available models to efficiently and effectively handle the space. Every model will let you know the best square footage to buy the one that fits the area the best.

  • Why should I consider increasing my budget if possible?

If you can increase your budget to purchase an air purifier, you might want to do that. This would help you purchase not only a bigger device if needed, but it can also help you get more features and a much more efficient and effective model. Figure out how much you can spend, and then check out the models that would fit your needs as well as your budget.

  • Why is the noise level something I need to consider?

For those who will be using these in your office or even your bedroom, you might not want a machine that would make a lot of noise. This is especially important if you are a light sleeper or if you would be using it for children since it might keep you up at night or wake you up.


Ensure that you are checking out all of these models and using the factors and features available to help you make a choice. It might not seem like an easy choice, especially if you are on a budget, but there are plenty of great and effective models out there that aren’t expensive. Ensure that you are looking at these models and picking the one to suit your needs the best.
