The living room is very spacious and therefore provides ample room in which to relax, entertain and spend time with your family. However, since there is more space there is also more air that has to be cleaned. Dust, pollen, pet dander, smoke and other airborne particles can spread all over the room as people move about and when the heating or cooling systems are operating.
Which is why it is important to take size into account when selecting an air purifier; an air purifier that performs well in a small bedroom might have difficulty in a large living room. When you are looking for the best air purifier for a large room, knowing about room coverage, airflow, and filtration can assist you in picking a model that really suits your space.
Why Room Size Matters
An air purifier takes the air from a room, passes it through filters, and then blows cleaner air back into the room. If it is to have a noticeable effect, it must regularly treat a sufficient amount of air.
In open-plan houses, the size of the room becomes even more significant. A purifier installed in the living room will probably have to deal with the air from a neighbouring dining area or kitchen.
Understanding CADR
The Clean Air Delivery Rate, or CADR, is one of the most useful figures to take into account when comparing air purifiers since it shows how rapidly an air cleaner can supply filtered air and is usually given for smoke, dust, and pollen.
Simply put, the higher the CADR, the more air the purifier will be able to move and clean. Before you decide to buy one, measure your room and compare its size with the CADR that the manufacturer recommends.
It’s a mistake to think that a purifier which is advertised as being suitable for a large area will work just as well at all fan settings. The faster you want the cleaning to be, the more important airflow becomes.
HEPA Filtration Is Only One Part
It is important to have HEPA filtration if you want to get rid of fine airborne particles, but the filter alone doesn’t tell the entire story.
For a purifier to function properly it needs adequate airflow so that the air in a room can pass through the filter. A highly efficient filter in a machine that is too small may not clean a large room as well as a correctly sized unit having sufficient airflow.
If smoke or odours are a concern, then you should look at a model that combines particle filtration with activated carbon; since particle and gas filtration deal with different kinds of pollutants, having both is useful for homes which have several sources of indoor pollution.
Consider Your Room’s Layout
It’s not just the square footage that makes a difference; the shape and arrangement of your room can influence how well the filtered air circulates. Before choosing a purifier, consider:
- Total room size and ceiling height
- Open or divided floor plan
- Number of people regularly using the space
- Pets and other sources of airborne particles
- Outdoor pollution entering the home
- How long you expect to run the purifier each day
They can assist you in deciding whether it is better to have one large unit or a number of smaller ones.
Placement Can Affect Performance
A large room air purifier of the highest quality will not be able to work at its full potential if the air flow is obstructed.
Do not position the unit behind any furniture, in a tight corner, or up against things which obstruct its intake or exhaust; it must have sufficient open space to take in and distribute the air.
In a big living room having a more central position could help the purifier to circulate the air more efficiently. You should always adhere to the placement recommendations given by the manufacturer.
It is convenient to have a single purifier since there is only one machine to run and one filter to look after. It might perform particularly well in a large, open room.
It makes more sense to have more than one unit if your home has separate bedrooms, offices, or other enclosed rooms, and you should position each purifier in the area where people spend the most time rather than having a single machine attempt to clean the whole house.Consider multiple units when:
- There are many distinct rooms in your house.
- The floor plan is either long or made up of separate sections.
- One purifier cannot cover enough area.
- Filtration is also wanted in the bedrooms as well as in the common areas.
- A single, large room can be adequately served by a purifier of the right size having good airflow.
Features Worth Considering
When you have decided on the amount of coverage and airflow required, then consider the features that can make the purifier easier to use.
- Air Quality Sensors: Certain models check the level of particles and then automatically vary the fan speed. It is convenient to have this feature when the air quality changes during the day.
- Multiple Fan Speeds: It is useful to use higher settings when pollution levels go up, but lower settings might be better when you’re sleeping, working or watching television.
- Filter Replacement Indicators: A replacement indicator will remind you that it’s time to attend to the filter, and regular maintenance is important since a full filter can have an effect on performance.
- Noise Levels: A purifier that is very powerful won’t be much use if you avoid using it since it’s too noisy, so you should check the noise level at the settings that you use most frequently.
How to Choose the Right Purifier
The most highly rated air purifiers are not necessarily the best choice for every large room; although reviews can be useful for comparing different models, your particular room and requirements should be given priority.
Conclusion
If you are looking for the best large room air purifier, you should first look at your room rather than the purifier itself. Take measurements of the room, take account of its arrangement, and decide which pollutants you would like to reduce. After that, compare the CADR, the filtration system, the coverage area, and the operating features.
