Learn how to replace the HEPA filter in your Lasko HF11200 table top air purifier. Follow these simple steps for cleaner air and better performance.
Quick Answer
To replace the HEPA filter in your Lasko HF11200 table top purifier, unplug the unit, remove the front cover, take out the old filter pack, insert a new Lasko LP200 filter pack (which includes both a True HEPA filter and an activated carbon filter), and reassemble. Replace every 6-12 months for best performance.
Why Regular Filter Replacement Matters
The Lasko HF11200 table top air purifier uses a 3-stage filtration system: a carbon filter, a VOC filter, and a pleated filter. Over time, these filters trap dust, pollen, pet dander, smoke, and odors. When they become clogged, airflow drops and the purifier cannot clean the air effectively. Replacing the filter pack every 6 to 12 months—or sooner if you notice reduced airflow or a musty smell—keeps your unit working as intended.
Step-by-Step Filter Replacement Guide
- Step 1: Unplug the Purifier: Always disconnect the power cord from the outlet before opening the unit. This prevents accidental activation and protects you from electrical shock. Common mistake: Forgetting to unplug can damage the electronics or cause injury.
- Step 2: Remove the Front Cover: Grasp the top of the front cover and gently pull it away from the main body. The cover is held by clips and should come off without excessive force. Checkpoint: If the cover feels stuck, check for any screws or latches you may have missed.
- Step 3: Take Out the Old Filter Pack: Slide the old filter pack out of the compartment. Dispose of it according to local regulations. Note that the pack includes both a HEPA filter and a carbon filter in one unit. Common mistake: Trying to clean and reuse a disposable filter—this reduces efficiency and may release trapped particles.
- Step 4: Insert the New Lasko LP200 Filter Pack: Remove the new filter pack from its packaging. Align it so the arrows on the filter point in the same direction as the airflow label inside the unit. Push it firmly into place until it sits flush. Checkpoint: Ensure the filter is oriented correctly; reversed installation blocks airflow.
- Step 5: Reattach the Front Cover and Plug In: Snap the front cover back onto the unit until it clicks securely. Plug the purifier back in and turn it on. Run it on high speed for a few minutes to confirm normal airflow. Final check: If you hear unusual noise or smell a burning odor, turn off and recheck the filter placement.
