Gone are the days of homes that are safe and secure for residential living; as globalization rises, indoor air quality is fast becoming a breeding ground for airborne pollutants. Known to be 5 times more polluted than outside air, poor indoor air quality is a slippery slope to a slew of respiratory and chronic illnesses when not properly dealt with.

Invisible, invasive, and intimidating without any traces left behind, these airborne particles are detrimental to human health. From allergens to mold and smoke particles, the list of air pollutants is endless. Hence, a powerful air purifier with a strong clean air delivery rate is essential to keep potential health conditions at bay through improved indoor air quality.

Overview of Large Room Air Purifiers

When it comes to choosing the right air purifier for confined spaces, the first criteria should always be dependent on the size of the home or office space. Not restricted to just living rooms, it is also important to decide if a single air purifier is sufficient for household usage.

Not too small to be an inefficient air cleaner and not too large to take up limited space, healthier air is easily within reach. In certain circumstances, a smaller air purifier might not be enough.

With average bedroom sizes of 132 sq ft in the US, larger rooms should be double the size aggregating around 300 sq ft. Therefore, a large air purifier that covers up to 1000 sq ft is often recommended. This helps to ensure that airflow in the room is purified more than once per hour for maximum efficacy.

These are the main advantages of the IQAir HealthPro Plus:

HEPA Filtration

Since ultra-fine particles make up over 90% of indoor air contaminants, it is vital for air purifiers to diligently eliminate pollutants below 0.1 microns in size. Due to the detrimental consequences such as heart attacks, strokes, asthma, and even cancer of these airborne contaminants, selecting an air purifier that removes these particles is essential.

By complying with the energy efficiency laws of the European Union and Switzerland, it facilitates the highest standard of existing product regulations. This ensures that each air purifier is safe and secure for long-term usage.

No matter the room size, the filtration system works efficiently with little replacement. This makes IQAir HealthPro Plus an extremely cost and environmentally-friendly product for homeowners looking to purify the air in large places.

Buying Guide: How to Pick the Right Air Purifier for Large Spaces

A large room is considered at least 350 sq ft yet below 1900 sq ft.

For an air purifier to meet your needs in a large room, it needs to be able to do three things: eradicate harmful airborne pollutants, circulate air with smart features, and have a high clean air delivery rate. As recommended by EPA, clean air needs to be purified at least 5 times an hour.

For the first one to take place, a special filtration system, including HEPA filters and activated carbon filters, needs to be in place. In addition, the type of air purifiers chosen also largely depends on the inhabitants of the house and the current air pollution level.

To help you choose better, here is a simple guideline to help you out.

Assess Your Surroundings

Before researching the type of air purifier, determine the air pollution level in your home. Start by assessing your surroundings and where you live. If you live in a city, consider checking out if you reside in a busy, road-filled street or the suburb where lush greenery is aplenty.

Depending on the location of your home, you can have a clearer idea of where to begin. For example, if you live on the first floor with windows facing a busy car-filled road, then you should consider a large air purifier that is more efficient with true HEPA filters that will trap all incoming airborne pollutants.

Determine Your Needs

Once you have an idea of your current home location, write down what you need. These things largely vary on several factors that are uncontrollable. To do a proper assessment, you need to be clear on why you need an air purifier. Start by listing down a range of reasons that contribute to your need for air purifiers; the common ones include:

  • Asthma, allergies, and respiratory symptoms
  • Prevent viral infections due to COVID 19 etc
  • Weakened immune system etc
  • Unnecessary air pollution externally (burning from neighbors, exhaust fumes, factory fumes)
  • Pungent odors from internal or external influences
  • Better health for you and the family

Once you are sure of why you need an air purifier, move on to the next step.

Measure Your Room Size

The size of your confined space plays a huge role in successful air purification. For the air purifiers to work, you need to ascertain the size of your home or large room. The room size can be tricky to measure. Hence, the most common way is to rely on actual valuation reports from your real estate agent.

If that proves to be difficult, consider these methods below on how to measure your room:

  • Check the floorplan and determine the actual size of your enclosed space
  • Consider doing it manually by using a pencil or measuring tape and having someone help you
    • Simply start by measuring the sides of the walls in length and width
    • Multiply the two numbers, and your room in sq ft should be accurate

A slight variation should not affect the effectiveness of your air cleaner in any shape or form.

Be Specific

Once you have the main details, go back to your list again. This time includes all the nitty gritty details you need to select the perfect air purifier. Reliant on your actual desires and preferences, your ideal air purifier very much depends on this list you have created. By identifying it as a ‘wants’ list, you can determine what is preferred but not absolutely mandatory.

Here is a simple list to guide you:

  • A smart air purifier that has auto modes to turn off through seamless adjustment
  • A visually appealing air purifier that comes in various colors for you to fit into your home
  • An environmentally friendly air purifier that aligns with your personal values
  • A silent air purifier with a non-existent noise level because you have light sleepers
  • An air purifier with more than one fan speed to fit your needs better
  • An air purifier that has an energy star rating to conserve energy for long-term cost savings

For people with smart homes, they tend to prefer devices that harmoniously synchronize effortlessly. In addition, clumsy and forgetful homeowners are usually recommended to get air purifiers that turn off automatically to prevent energy wastage to save utility costs.

Technical Expectations

Once you have decided on the above, move on to the actual air purifier technicalities you need. For people with enclosed areas above 1000 sq ft, choosing a large air purifier that caters to additional space is vital. This ensures air is circulated multiple times to keep it clean, fresh, and consistently high quality.

Here are some of the technical aspects to determine for your air purifier:

One pro tip is also to decide how many air purifiers you need in a large room. Some people prefer having many small air purifiers in a home, while some just want to invest in a one-fits-all large air purifier. 

Placement of an Air Purifier for a Large Room

The only way for an air purifier to work is for it to do its job: uninterrupted. For that to happen, it is essential to place your air purifier strategically to draw in air unobstructed to continue circulation effectively. In the right place, it can increase efficiency by 20%. With poor placements, such as behind a television or cupboard, you lose over 50% of efficacy.

To guide you in the right direction, follow these 7 simple steps to help you get started:

  1. Leave air purifiers closest to the source and highest concentration of pollutants
  2. Put your air purifiers 3 – 5 feet above the ground
  3. Keep your air purifiers in areas with the highest air circulation levels such as doorways or windows
  4. Be mindful not to put your air purifier in a corner
  5. Make sure the air purifier is a standalone device with no blockage or visible obstruction
  6. Avoid high humidity areas as it lessens the efficiency of HEPA filters
  7. Do not leave it close to electronic products to prevent electronic interference

A quick tip is to consider mounting your air purifier on a wall instead of leaving it around. Horizontally or vertically installing it helps ensure airflow is unobstructed or blocked from various room areas.

How to Calculate What Size Air Purifier You Need?

To choose the best air purifier for your home, the size is largely dependent on the sq ft of your home. By focusing on finding an air purifier that can purify air more than once an hour within your designated size, it would be the most ideal situation for most homeowners.

Known as the clean air delivery rate (CADR), you can use this basic guideline below to select the best air purifiers for you.

Our Testing Process

By putting the initial expectations in place, we note down the pros and cons of each air purifier before categorizing them based on varying needs.
