The Sharp FP-F30J-H is a compact, three-speed purifier specified for rooms of about 21 m² under Sharp’s stated test method. It could suit someone who finds a working unit at a sensible price, but its 21 m² figure is not a universal room-size guarantee, and the model is listed as discontinued. Check that the correct FZ-F30HFE replacement filter is available before buying. The available evidence provides manufacturer specifications and CHOICE listing details, but not a public CADR figure or accessible independent noise and performance scores.
Is the Sharp FP-F30J-H worth buying?
It is a plausible choice for a small room if you can confirm the purifier is in good condition, the price reflects its discontinued status, and FZ-F30HFE filters are obtainable. Its useful strengths on paper are a modest 4 kg weight, three airflow settings, a HEPA filter, and a stated room-size figure of approximately 21 m². The main drawbacks are uncertainty around current stock and future support, plus the absence of a published CADR figure in CHOICE’s listing.
This is a specification-led assessment rather than a claim of hands-on testing. CHOICE lists the FP-F30J-H as discontinued and reports a one-year warranty, but the available information does not establish current retailer inventory, transaction prices, or what warranty and parts support remain after discontinuation. CHOICE’s detailed expert scores and noise measurements are member-only on the page consulted, so they cannot support a claim that the unit performed particularly well or quietly in independent testing.

- Someone looking for a relatively small purifier for a room around the scale of Sharp’s stated 21 m² rating.
- A buyer who can verify that the unit works and can source the specified replacement filter, rather than relying on a listing that says only “compatible.”
- A buyer willing to accept more uncertainty about long-term parts and warranty support than with a currently sold model.
Who should look elsewhere?
- Anyone who needs a clearly published CADR to compare air-cleaning performance across models.
- Someone who needs confidently verified current filter stock or ongoing manufacturer support before committing.
- Anyone whose room size or air-cleaning needs exceed what can reasonably be inferred from the product’s stated test-based room-size figures.
What room size is the FP-F30J-H designed for?
Sharp gives an approximate 21 m² recommended room size for dust removal under the JEM1467 test definition. That is a specific test-based figure, not a guarantee that the purifier will provide the same cleaning rate in every 21 m² room.

The separate 16 m² figure associated with Plasmacluster is based on an ion-concentration test setup. It measures a different aspect of the product under a different method, so it should not be substituted for the 21 m² dust-removal figure or treated as a competing version of the same rating.
| Figure | What it describes | How to use it |
|---|---|---|
| Approximately 21 m² | Recommended room size for dust removal using Sharp’s JEM1467 definition. | Use as the product’s stated dust-removal room-size reference, not a promise of identical results in all rooms. |
| Approximately 16 m² | Plasmacluster recommended room size under a separate ion-concentration test setup. | Keep it distinct from the dust-removal rating; the test purpose and method differ. |
CHOICE does not state a CADR for this model. A room-size claim alone cannot be converted into a CADR, so there is no supported basis here for comparing the FP-F30J-H with another purifier on that measure.
What airflow, power and physical specifications does it have?
Sharp’s operation manual lists three fan settings. Maximum airflow is 180 m³/h, medium is 120 m³/h, and sleep is 60 m³/h; rated power is 51 W, 30 W, and 13 W respectively. The manual also gives standby power of about 1.0 W.
| Setting | Airflow | Rated power |
|---|---|---|
| MAX | 180 m³/h | 51 W |
| MED | 120 m³/h | 30 W |
| SLEEP | 60 m³/h | 13 W |
| Standby | Not stated | About 1.0 W |
Those figures make the trade-off between airflow and rated power clear: the higher settings move more air and use more power, while sleep mode uses the least power of the three operating modes and has the lowest listed airflow. The manual’s figures do not establish how loud the settings sound; no usable noise measurements are available here.

The manual specifies dimensions of 400 × 182 × 463 mm, or 40 × 18.2 × 46.3 cm, a weight of 4.0 kg, and a 2.0 m cord. CHOICE lists the dimensions rounded to 46 × 40 × 18 cm and the weight as 4 kg. The small difference in the order and rounding of dimensions is not a different model specification.
How does the FP-F30J-H filter air?
The purifier has a pre-filter and a HEPA filter, and Sharp also describes Plasmacluster ion treatment. The manual says the HEPA filter traps 99.97% of particles as small as 0.3 microns when air passes through the filter system. That is a filter-performance claim for particles passing through it; it is not a measured guarantee that 99.97% of all particles in an entire room will be removed in a particular period.
The distinction matters when interpreting the headline number. Room cleaning depends on more than the filter’s capture figure, including airflow and room conditions. Sharp’s stated room-size test offers a separate reference for dust removal, while the CHOICE listing’s lack of a CADR means there is no published CADR value here for a like-for-like comparison with products that report one.
Which replacement filter does the FP-F30J-H use?
The specified replacement filter is Sharp FZ-F30HFE. Confirm that exact part number against the product listing or packaging before ordering; a generic claim that a filter “fits Sharp” does not establish compatibility with this model.

CHOICE lists the replacement filter at $69 as a reference price. That is not a verified live transaction price, and the available information does not establish current stock. Because the FP-F30J-H is listed as discontinued, checking filter availability before purchasing the purifier is especially important: the machine is a less practical buy if the required consumable cannot be replenished.
How often should the filter be replaced?
CHOICE reports a 6–12 month or alert-based replacement interval. The manual gives a different, conditional guideline: about two years under a stated use condition of five cigarettes per day. It also cautions that actual filter life varies with the room environment, usage, and the unit’s location. These figures are not a single guaranteed service life; follow the unit’s filter alert and instructions, and account for the conditions in which it operates.
The manual identifies FZ-F30HFE as the replacement part. It does not recommend washing and reusing the HEPA filter. A filter that has been washed or reused should not be treated as a fresh replacement with its original stated performance.
What does the FP-F30J-H cost to own?
CHOICE reports a $339 reference price for the purifier and $69 for a replacement filter. These are listing reference points, not confirmed current prices or guarantees of availability. The product’s current purchase cost may differ, and ongoing filter expense depends on the interval that applies to the room and usage rather than a fixed schedule for every owner.

Since the model is listed as discontinued, include parts availability in the ownership decision rather than comparing the initial purchase price alone. Before buying, verify the seller’s return terms, whether the supplied unit is complete and functional, and whether you can obtain FZ-F30HFE filters. The available information does not confirm post-discontinuation warranty support, so do not assume the one-year warranty reported by CHOICE is still available for a particular used or remaining-stock unit.
Is the Sharp FP-F30J-H discontinued?
Yes. CHOICE lists the FP-F30J-H as discontinued. That status does not prove that every retailer has run out of stock, but it does mean a listing’s presence should not be taken as evidence of reliable ongoing supply or support.
CHOICE also lists a one-year warranty and Thailand as the country of origin. The one-year figure is a listing detail, not confirmation of coverage for a specific purchase today; establish the terms directly with the seller, particularly for used units or old stock. Current retailer stock and post-discontinuation parts or service support have not been verified.

- Confirm the exact model. Check the FP-F30J-H model designation on the unit or its documentation, not only in a seller’s headline.
- Check the filter part number. Ask whether Sharp FZ-F30HFE is available and verify compatibility before treating a substitute as suitable.
- Clarify condition and return terms. For used or old-stock units, confirm what is included, whether it operates, and how returns are handled if it does not.
- Ask about warranty coverage. CHOICE lists a one-year warranty, but the coverage applicable to the specific sale and current support arrangements are not established by that listing.
- Match the room claim to your need. Treat approximately 21 m² as Sharp’s JEM1467 dust-removal reference; do not equate the separate 16 m² Plasmacluster figure with the same test.
- Compare what is actually published. The available CHOICE page does not provide public noise measurements or expert scores, and its listing does not state a CADR. Do not fill those gaps with assumptions based on the room-size number.
If any seller cannot confirm the model, correct filter compatibility, or meaningful return and warranty terms, the lower upfront price may not compensate for the uncertainty of owning a discontinued purifier.
Frequently Asked Questions
Can I wash the Sharp FP-F30J-H HEPA filter?
No. Sharp’s operation manual says not to wash and reuse the filter. Washing it does not restore it to a new-filter condition or establish that it will retain the stated filtration performance.
Does the FP-F30J-H remove odors and gases as well as particles?
The cited manual claim is specifically about trapping particles as air passes through the HEPA filter. The available specifications do not establish an odor- or gas-removal rate, so do not read the particle-capture percentage as evidence of performance against gases.

Does the Sharp FP-F30J-H have an automatic fan mode?
The manual settings identified for the FP-F30J-H are MAX, MED, and SLEEP. The available specification does not identify an automatic fan setting, so confirm the actual controls on a specific unit if that feature is important to you.
