Best air purifier for large rooms buying guide

If you’re having trouble with air quality in your home, it may be time to purchase an air purifier. Air purifiers come in many shapes and sizes, but we will focus on air purifiers for large rooms. We know that air pollution is a significant problem for those who live near cities and traffic areas. If you are looking for the best air purifier for large rooms, this buying guide will help you through the process of finding one that fits your needs.

Cost of replacement filters

As a general rule, you should replace filters as recommended by the air purifier manufacturer. Replacement filters can range from as little as $30 to well over $100 for a set of three or four air filter cartridges, depending on the size and design of your air purifier. Ideally, air filter replacement should coincide with seasonal changes, so you don’t forget and let it go too long between replacements! Suppose you have allergies, asthma, or other respiratory conditions that require frequent monitoring of air quality in the home. In that case, we recommend choosing an air cleaner with washable HEPA-type filters, which will save you money since they won’t need to be replaced regularly.

Room size

If an air purifier has an AHAM Verified seal, you can be confident that it has been tested for air cleaning performance in a room of the size recommended by AHAM. For example, an air purifier with a 200 sq ft room size recommendation is suitable for rooms up to 150 square meters (about 1600 cubic feet). It will be effective against pollutants like dust, pollen, and pet dander at concentrations equal to or greater than those allowed by AHAM’s standard.


The last thing we will consider is noise. Air purifiers in large rooms are a little noisy. So it is necessary to know the sound level in decibels and choose air purifiers that meet your needs. For example, air purifiers with a noise of 42 dB will be perfect for bedrooms and living rooms, and air purifiers up to 52 dB can work well in offices or open spaces.

There are so many different models on the market, but not all of them effectively remove allergens and particles from the air. We’ve compiled a list of FAQs about buying the best air purifier for large rooms in your home or office. Read on if you want to know more!

Q. What size room do I want it for?

If you are looking to buy one, then the best idea is that if your bedroom or area where it will be kept fits into specific square footage (measurement of interior space in a building) range, then this should already give you a good indication of what size purifier that you need to get, e.g. small, medium and large. Small rooms require less power, so they might not have as much coverage, but they can still filter out some particles from the air, which may help with breathing problems, allergies, etc. Large areas require more power, so these kinds of purifiers tend to use multiple filters because there are just too many different things being emitted from the air.

Q. What type of filters should I get?

You should be getting a filter that can remove the particles you are most concerned about from your home. If it’s pollen, dust, or mould allergies, get an H13 HEPA filter if you need to clean the air in a small room such as an office cubicle or bedroom, contact, e.g. small and medium-sized filters.

Q. How often should I change my filter?

Once the particles or allergens are removed, your filter is no longer effective. If you’re not sure how long it takes for this to happen (it varies depending on what type of pollutant you need to be filtered out), then make a point to change the filters every six months at least.

Q. Do air purifiers work in large rooms?
