Howard Leight Maximum Lite Cordless Earplugs, LPF-1 NRR 30 (Low-Pressure Foam) Overview
The Howard Leight Maximum Lite cordless earplugs (LPF-1) are single-use, low-pressure foam hearing protection rated NRR 30 in the US. Under OSHA 1910.95, hearing protection is required when noise reaches an 8-hour time-weighted average of 85 dBA, and a well-fitted foam plug like this is a comfortable first line of defense for high-noise work.
As low-pressure foam earplugs, the draw is all-day comfort: the foam expands gently to reduce that plugged, high-pressure feeling, a contoured T-shape lets you insert without touching the part that enters the ear, and the smaller-diameter body makes these smaller ear canal earplugs that seal where bulkier plugs do not. As disposable foam earplugs in green with a soil-resistant skin, they stay clean and easy to spot. This is the Max Lite NRR 30 plug in its uncorded form.
Like any item in hearing protection, match the plug to your measured noise exposure rather than reaching for the highest number. As uncorded plugs the Howard Leight LPF-1 avoids a cord that could snag; the same Max Lite plug is sold corded as the LPF-30. Compare this foam ear plug against other NRR 30 plugs and cordless options before ordering.
What These Max Lite Earplugs Are Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| High-noise industrial work | Purpose-built | NRR 30 covers most workplace noise when fitted correctly. |
| Long shifts / all-day comfort | Strong | Low-pressure foam expands gently to reduce that plugged feeling. |
| Smaller ear canals | Strong | The smaller-diameter body seats where standard plugs feel bulky. |
| Snag-risk areas (moving equipment) | Good | Uncorded avoids a cord catching; choose the corded LPF-30 to avoid drops. |
| Repeated all-day reuse | Not ideal | Single-use; for daily reuse choose a washable reusable earplug. |
Hearing protection only works when it fits. The labeled NRR is a laboratory value that overstates real-world attenuation, so OSHA and NIOSH recommend derating it β a common method subtracts 7 from the NRR and halves the remainder when estimating protection against a time-weighted average exposure. Wear hearing protection whenever noise reaches an 8-hour TWA of 85 dBA under OSHA 1910.95, roll and insert each foam plug fully and hold until it expands, replace plugs that will not seal, and use dual protection (plugs plus muffs) only per your safety program for very high noise.

Pros & Cons
- NRR 30 attenuation for high-noise work
- Low-pressure foam for gentle, comfortable all-day wear
- Contoured T-shape eases hygienic insertion
- Smaller-diameter body suits smaller ear canals
- Uncorded to avoid snags (corded LPF-30 also available)
- Single-use β not a washable reusable plug
- Uncorded β easier to drop than the corded LPF-30
- Field attenuation depends on fit; derate the labeled NRR
- NRR 30, not the NRR 33 of the firmer Maximum plug
How It Compares
The Max Lite LPF-1 is the low-pressure, uncorded disposable option. Weigh it against the alternatives before ordering:
| Option | Form | NRR | Best for |
|---|---|---|---|
| Max Lite LPF-1 (this page) | Uncorded low-pressure foam | 30 | Comfortable high-noise use |
| Max Lite LPF-30 (corded) | Corded low-pressure foam | 30 | Preventing dropped plugs |
| Maximum (Max) foam | Firmer disposable foam | 33 | The loudest environments |
Choose the uncorded LPF-1 for comfortable disposable protection, the corded LPF-30 to avoid drops, or the firmer NRR 33 Maximum for the loudest work. Compare in our best foam ear plugs guide and the wider hearing protection range.

Frequently Asked Questions
Are the Maximum Lite LPF-1 earplugs corded or uncorded?
The LPF-1 is the uncorded (cordless) version. Howard Leight sells the same Max Lite plug with a cord as the LPF-30 for applications where a neck cord helps prevent dropping. Choose the uncorded LPF-1 where a cord could snag on equipment.
What is the NRR of the Max Lite LPF-1?
The Max Lite LPF-1 is rated NRR 30 in the US, a strong rating for a disposable foam plug. NRR is a laboratory value, so derate it for real-world use rather than assuming full protection. It suits most industrial noise when fitted correctly.
What does low-pressure foam mean?
Low-pressure foam expands more gently in the ear canal than standard foam, reducing the outward pressure and that plugged, uncomfortable feeling during long shifts. The trade-off is a softer feel; insert fully and confirm a seal, since comfort should not come at the cost of fit.
Do they fit smaller ear canals?
Yes. The Max Lite has a smaller-diameter body designed to fit smaller ear canals more comfortably than a standard large foam plug, while still sealing. If standard foam plugs feel too bulky, this is a good option to try.
What are the earplugs made of?
Low-pressure polyurethane foam with a smooth, soil-resistant skin. The foam compresses for insertion and expands to seal the canal, and the skin resists dirt buildup in dusty workplaces. The plug is green for easy identification.
How do I insert the LPF-1 correctly?
Roll the foam down to a thin crease with clean fingers, reach over your head to pull the ear up and back, insert the plug well into the canal, and hold it while the foam expands. A shallow fit loses much of the rated protection, so reinsert if you can still hear normally.
How should I apply the NRR to real noise levels?
OSHA and NIOSH recommend derating the labeled NRR because lab conditions overstate field performance. A common OSHA method subtracts 7 from the NRR and halves the remainder when estimating protection against a time-weighted average exposure. Follow your safety program's method.
When is hearing protection required?
OSHA requires hearing protection when noise reaches or exceeds an 8-hour time-weighted average of 85 dBA under 1910.95. If you must raise your voice to be heard at arm's length, noise is likely high enough to warrant protection. See our guide on when hearing protection is needed.
Can I use these with earmuffs for very loud work?
Yes. Dual protection - earplugs plus earmuffs - is used for very high noise, but the combined NRR is not the sum of the two. Add about 5 dB to the higher of the two device ratings as a rule of thumb, and follow your safety program for dual-protection thresholds.
Are the Max Lite LPF-1 reusable?
They are single-use disposable plugs. You can reuse a pair briefly if they stay clean and keep their shape, but discard them once they are dirty, will not expand, or no longer seal. For repeated daily wear, a washable reusable earplug is a better fit.
How is the LPF-1 different from the NRR 33 Maximum?
The Max Lite LPF-1 is NRR 30 low-pressure foam for gentle comfort. Howard Leight's Maximum (Max) is a different, firmer plug rated NRR 33 for the loudest work. Choose the higher rating only when your measured noise calls for it.
How are the LPF-1 earplugs packaged?
The Max Lite LPF-1 is sold in various pack and dispenser sizes for stocking a crew or workplace. Check the packaging for the exact pair count and choose the pack that matches how you issue and replace plugs.
