Corsi Rosenthal Box: Get to Know the Basics!

The Corsi Rosenthal box is an inexpensive way to purify the air in your home. People love its idea because not only is it an affordable alternative to expensive air purifiers, but it really works without needing major technical skills!

Many call the Corsi Rosenthal a "DIY air purifier" because you need to assemble it using everyday parts: a box fan, furnace filters, and some cardboard or tape. In fact, you can also call it a C-R box or even a box fan air filter system.

Interestingly, many of our customers buy filters specifically to build these Corsi Rosenthal boxes for their homes.

A Corsi Rosenthal box usually uses four or five furnace filters that are arranged in a pentagon or square shape around a basic fan. Then, you seal gaps with cardboard or tape, which creates an airflow that pulls contaminated air through the filters and pushes our cleaner air.

You can build a homemade filter setup this way and easily remove dust, allergens, smoke particles, and other pollutants from your indoor space.

Why Is It a Premium DIY Air Purifier?

The concept of the Corsi Rosenthal box became more than a trend in many households that needed an extra boost in air filtration, especially during wildfire seasons and COVID-19. When you compare the Corsi Rosenthal box to a standard air cleaner, you'll notice that it's significantly more affordable yet still provides excellent results.

We also see it as a chance for people to repurpose an extra box fan air filter or leftover cardboard. That's what DIY is all about: using what you have on hand and saving on costs!

A Corsi Rosenthal box uses simple, on-hand parts you might already have around at home.

 

What are the Key Components of a Fan Filter Box?

A Corsi Rosenthal box uses simple, on-hand parts you might already have around at home. The key components of this DIY air purifier include:

  • 1 standard box fan that fits snugly on the side or top

  • 4 or 5 furnace filters (often 20x20 in size)

  • Cardboard or tape for securing the structure

  • Scissors and a marker for cutting and labelling

We noticed that the UF13-22020-4 and UF13-22020-12 are highly popular among our satisfied customers.

These numbers refer to our packs of high MERV filters, which are perfect for the Corsi Rosenthal box design. It's always smart to use MERV 13 filters, as these can capture even the tiniest particles, including some microorganisms and smoke.

That said, some people prefer MERV 11 furnace filters for a DIY air purifier because they allow for even easier airflow.

If you're looking for the highest filtration, it's best to pick MERV 13, but MERV 11 is also a great option.

Why Get MERV 13 Furnace Filters?

As you know now, MERV 13 furnace filters are the best! A Corsi Rosenthal box works best when it uses filters that can trap finer particles.

An average MERV 13 furnace filter can capture pollutants in the 1.0-3.0 micron range, which covers a lot of airborne dust and various allergens. If you or someone in your family suffers from allergies, choose MERV 13 furnace filters.

Many people agree that MERV 13 is one of the best air filters for furnace systems and homemade filter projects.

We produce our MERV 13 filters with synthetic media that balances airflow and efficiency. As such, you can run the fan filter box without worrying about your fan overworking.

DIY Air Purifier: How to Build Your C-R Box Step by Step

Are you eager to make your own DIY air purifier? Here's how to do it in just 5 fool-proof steps!

  • Get your filters: It's best to use four or five 20x20 filters, but it depends on which design you're following. Our most popular options are UF13-22020-4 or UF13-22020-12.

  • Create the box: Arrange the filters so their airflow points inward. Secure them at the edges with tape to form a stable shape.

  • Attach the fan: Put the fan on top or the side (depending on your preference). Make sure it's sealed firmly so air is forced through the filters.

  • Cover any openings: With some cardboard or filter cutouts, cover small gaps to create a top seal.

  • Plug it in: Turn on the fan and check for any leaks. If you follow these instructions step-by-step, you'll get a fan filter box that circulates air inside your home through high-efficiency furnace filters.

It's easy to see what makes this DIY air purifier a hit. If you're into do-it-yourself projects that take no time, you'll want to build a homemade filter system today.

On average, it should take around one hour or less to complete.

One of the biggest benefits of building your fan filter box is that you can control the filters and see how dirty they get over time. To extend the life of your DIY air purifier, here's what you can do.

 

How Can I Extend Filter Life Easily?

One of the biggest benefits of building your fan filter box is that you can control the filters and see how dirty they get over time. To extend the life of your DIY air purifier, here's what you can do.

  • Keep your space clean: Vacuum carpets and wipe surfaces regularly. If you have less dust in your room, you'll also have less dust in the filters.

  • Vacuum the exterior of the filters: You can do this occasionally to remove dust or large debris that can get stuck.

  • Run the Corsi Rosenthal box only as needed: If the indoor air quality (IAQ) in your home is generally good, you can use the Corsi Rosenthal box occasionally. By doing so, you'll save energy and extend the lifespan of the filter.

When it's time to swap filters in your DIY air purifier, just remove the old ones and tape new ones in place.

5 Cool Ways a Corsi Rosenthal Box Works for IAQ

Why should anyone make a homemade filter? How does the Corsi Rosenthal box quickly improve indoor air quality? Check these out!

  • Top efficiency filtration: You can use MERV 11 or MERV 13 filters in your Corsi Rosenthal box to trap a wide range of pollutants. These can even work with some bacteria or viruses.

  • Active airflow: The box fan is powerful enough to pull air through the filters, which means continuous airflow. A DIY air purifier needs consistent airflow to be effective, and that's precisely what you get with a C-R box.

  • 360-degree intake: This DIY air purifier includes multiple filters arranged in a cube. So, the air can be drawn in from several directions, allowing for better circulation throughout the room compared to single-filter designs.

  • Cost-effective option: A store-bought air purifier can be costly. A fan filter box that uses materials can often cost less per unit, making it more accessible for budget-friendly families or school classrooms.

  • Easy to maintain: A DIY air purifier doesn't need much upkeep. You can see when the filters are dirty and then replace them quickly as needed.

All in all, this DIY air purifier can be the best thing that can happen to your home. It’s a must-have for families with allergies or sensitivities or generally in spaces where indoor air quality might be compromised.

A Corsi Rosenthal box is an effective do-it-yourself air purifier. This DIY air purifier features a fan box, 4 or 5 furnace filters, and some cardboard or tape.
