How to Make a Sploof | DIY Guide + When to Just Buy One

The DIY sploof is one of the oldest improvised solutions in the smoker's toolkit. Anyone who has needed one in a pinch has made one. It works, partially and temporarily, and it costs almost nothing. This page covers how to make one correctly, what to expect from it, and where it falls short compared to a properly designed HEPA sploof.

The Classic DIY Sploof: What You Need

The original version requires three things: a toilet paper roll or paper towel roll cut down, dryer sheets, and something to hold them in place, a rubber band or tape.

Toilet paper tube works fine. A plastic water bottle with the bottom cut off works better because it has a more rigid housing. Either way, the core principle is the same.

How to Make a DIY Sploof: Step by Step

Step 1. Collect your materials: an empty toilet paper roll (or a 16-oz plastic water bottle with the bottom cut off), 3-4 dryer sheets, and a rubber band or tape.

Step 2. Stuff the dryer sheets into the tube. Pack them loosely enough that air can pass through, but tightly enough that the sheets make contact with the air stream.

Step 3. Fold one or two dryer sheets over the end you will exhale into and secure with a rubber band. This is the entry point. You will press your lips here and exhale.

Step 4. The other end is the exit. Leave it open, or loosely secure one more dryer sheet over it to catch any loose fibers.

That is it. Exhale through the dryer-sheet end. The air passes through the sheets and exits the other end with reduced odor.

How Well Does It Work?

For odor reduction: modestly, and temporarily. Dryer sheets contain fragrance compounds that mask smoke smell rather than filtering it. They are not activated carbon. They add a scent on top of the smoke odor rather than removing the odor compounds themselves. For light, occasional use in a low-stakes situation, it is better than nothing.

For particle filtration: not at all. Dryer sheets do not trap smoke particles. The visible component of your exhale passes through a DIY sploof without being captured.

For longevity: very short. Dryer sheets saturate quickly. After a few sessions, the fragrance is spent and odor masking diminishes significantly.

The Water Bottle Version

A plastic water bottle (16-20 oz) with the bottom cut off is a slight upgrade over a toilet paper roll. The rigid housing is more durable and holds its shape better. Fill the bottle with dryer sheets, cap the open bottom with a sheet held by a rubber band, and exhale through the drinking spout.

The limitation is the same: no activated carbon, no HEPA, no moisture management.

When the DIY Option Is Fine

In a genuine pinch, with no other option available, a DIY sploof is a reasonable improvisation. The cost is essentially zero and the build time is under two minutes.

When You Need Something Better

For regular use, a DIY sploof is the wrong tool. No particle filtration. No activated carbon. Rapid degradation.

Smoke Eraser uses real HEPA filtration and activated carbon. It has a removable prefilter that limits moisture and resin from reaching the HEPA filter. The HEPA filter is dried rather than replaced. Light to average users may never even clog it. Heavy users run them in rotation with a Docking Station for overnight recovery.

Over time, a maintained Smoke Eraser is more cost-efficient than a continuous supply of DIY materials, and it actually filters both odor and visible smoke rather than masking one partially.

The Bottom Line

For an emergency, the DIY sploof works. For regular use, the category has evolved significantly beyond dryer sheets and toilet paper tubes. A HEPA and carbon sploof performs better, lasts longer, and costs less over time.

Frequently Asked Questions

What dryer sheets work best for a DIY sploof?

Standard dryer sheets work. Unscented dryer sheets used alongside activated carbon granules will perform better than scented sheets alone since activated carbon actually adsorbs odor rather than masking it. A commercial HEPA sploof still outperforms any DIY version.

How many dryer sheets do I need?

Three to five, depending on the size of your tube. Pack them so air can move through but the sheets are in contact with the airstream.

How long does a DIY sploof last?

A few sessions at most before the dryer sheets are spent. Replace the sheets when odor reduction noticeably diminishes. There is no maintenance or recovery option.

Is a homemade sploof as effective as a commercial one?

No. A DIY sploof with dryer sheets provides partial odor masking and no particle filtration. A commercial HEPA and carbon sploof like Smoke Eraser provides genuine odor adsorption and visible smoke particle capture. The difference is significant.

Can I add activated carbon to a DIY sploof?

Yes. Activated carbon granules sold for aquarium filtration can be packed into a DIY housing. This improves odor removal but still does not provide HEPA particle filtration.
