Main trade-off
Nama J3
The smaller format can mean more loading during a larger recipe.
Head-to-head
Choose the H310A when the smallest listed body and lower lifting weight matter most. Choose the J3 when you prefer its wider batch format and have room for it. Both clear a 17-inch closed-height storage screen.
Before you choose
J3 is fractionally shorter, but H310A is 2.2 lb lighter. A cupboard-storage buyer should therefore separate height from lifting. Both pass a 17-inch closed-height screen, so weight and available width can make H310A the more useful fit.
What this is based on
J3 15.4 inches and 9.7 lb. H310A 15.5 inches and 7.5 lb. Heights exclude open lids.
Main trade-off
The smaller format can mean more loading during a larger recipe.
Main trade-off
The 15-minute continuous-use limit matters for a long preparation session.


Nama J3 vs Hurom H310A: compare height, listed body rectangle and the practical limits that change which juicer fits your daily routine.
Choose the H310A when the smallest listed body and lower lifting weight matter most. Choose the J3 when you prefer its wider batch format and have room for it. Both clear a 17-inch closed-height storage screen.
Winner by situation
H310A is lighter by 2.2 lb.
H310A has the narrower listed body.
Both are below that height.
H310A limit is known and J3 needs an exact manual check.
What matters in practice
J3 is fractionally shorter, but H310A is 2.2 lb lighter. A cupboard-storage buyer should therefore separate height from lifting. Both pass a 17-inch closed-height screen, so weight and available width can make H310A the more useful fit.
J3 15.4 inches and 9.7 lb. H310A 15.5 inches and 7.5 lb. Heights exclude open lids.
H310A has a listed body rectangle about 28% smaller. That is useful where a cutting board and juicer share the same surface. Neither rectangle includes the collection container, so check the entire station rather than assuming the remaining space is all usable.
J3 8.9 × 6.5 = 57.85 square inches. H310A 6.2 × 6.75 = 41.85. Reduction is 27.7%.
H310A permits up to 15 minutes of continuous operation. That is worth checking if a compact appliance will also serve visiting family or several different recipes. We have not established a matched J3 continuous-use limit here, so this is a required check rather than a claim that J3 can run longer.
H310A exact product page lists 15-minute standard usage. J3 duty-cycle value remains unfilled until the exact manual is checked.

A small mesh-free machine that is easier to place on a low shelf, with a shorter permitted continuous run than the larger Hurom models.
Meaningful differences
| What changes | Nama J3 | Hurom H310A | Why it matters |
|---|---|---|---|
| Height | 15.4 inches | 15.5 inches | The 0.1-inch difference is too small to replace measuring your actual shelf. |
| Listed body rectangle | 8.9 by 6.5 inches | 6.2 by 6.75 inches | H310A is narrower and has a smaller bounding rectangle. |
| Weight | 9.7 lb | 7.5 lb | H310A removes 2.2 lb from each lift. |
| Separation | Strainer-based chamber | Strainer-free two-part auger | H310A changes the screen-cleaning step. |
What you give up
Recommendation switch
Choose Nama J3. J3 offers batch loading in a 15.4-inch-high body, provided its wider footprint fits.
Choose Hurom H310A. H310A is 2.2 lb lighter and has the smaller listed width-depth rectangle.
Choose neither. The matched J3 duty-cycle value has not been established in this comparison.
